I have an HP 6475B with A10 CPU.
I used Linux Fedora 18, and recently updated to Fedora 19 (X64).
Everything works beautifully, and quickly !
With Fedora 19, you have to install the Broadcom drivers after install.
Other than that, the touch-pad driver works well, but unlike Windows 7, does not allow to be disabled by double tapping on the notepad G spot.
Skype works well (better than Windows).
The Brother Printer did not work out of the box, but a reinstall of the driver (one click-install!) from the Brother web site fixed that !
My external USB HP speakers work perfectly.
Bluetooth connection with smart phone work.
I would say this is a superb Linux, with a superb hardware.

Model used: A6-4400m
The 6475b laptop does not have any wlan card bios locking, so you are free to swap wifi cards as required.
I'm using the Intel Centrino 6200 card as it works straight out of the box (OpenSUSE12.3). I gave up with the broadcom 5ghz card that it came with; worked ok on oSUSE 12.1, but not with 12.3 (in place upgrade via repo changes).

Installing the official AMD catalyst drivers (13.4 at the time of write) and once the compiling prerequisites were met, just made the graphics acceleration & keyboard brightness control work - no xorg tweaks.

update:
brightness control (fn+f9/10) works on kernel '3.7.10-1.4-desktop' (kernel-desktop-3.7.10-1.4.1). Stops working on '3.7.10-1.11-desktop' (kernel-desktop-3.7.10-1.11.1).

Just got mine last week. Had to spend all weekend getting it configured, however, I have most everything working in Linux (Gentoo) apart from the web cam and fingerprint reader. I haven't actually tried getting either of these devices working yet so I cannot say whether or not they will work in Linux.

I am running Gentoo with a vanilla 3.4.4 kernel. I had to use the proprietary Broadcom “wl” driver to get the a/b/g/n card working, however, it does seem to work quite fine through ACPI sleep/suspend cycles. Also, I recommend building the Intel iwlagn stack as a module so that this forces the kernel configuration to expose the TKIP and other various encryption features that are required for WPA encrypted access points.

I am using AMD/ATI's proprietary firegl driver, version 12.6, with XOrg server 1.12.2 and everything seems to be working fine. I even have OpenGL acceleration, etc. working just fine. I would caution that the AMD driver stack will not auto detect the GPU so you will have to manually add the driver section into your xorg.conf to specify where the card is located on the PCI bus.

Getting screen dimming to work was a bit of a pain in the ass since HP have decided to make such a thing controlled via software… Pressing FN + F9/F10 doesn't do anything directly to hardware and, consequently, these key presses must be captured. To be honest, I'm not sure how I got this working other than to say that made sure to compile the kernel with LED backlight/video. However I made it work, it _does_ work–but so far only in X.

Sound works fine although you have to remember that you get two sound devices. One is the proper audio which conforms to the Intel HD standard and the other the HDMI audio.

As has been reported, there seems to be no way to influence the processor performance (P and C states), however, the “embedded” behaviour that AMD have engineered into the processor and GPU seems to be pretty good. It clocks up in an instant when needed and clocks down when not in use. My processor spends most of its time in deep sleep so I get excellent battery life (~7 hours in Linux doing basic web browsing, etc w/ the standard 55Wh battery).

Bluetooth seems to “just work” and didn't require any special tweaking other than to make sure that I build it into the kernel… I'm currently using a BT mouse that works just fine.
