Notes

I installed Debian Wheezy 7.0 beta1 (64bit) on it, which went perfectly fine. I did have some problems with not having the radeon firmware installed. After installing that, even KMS works okay.
Also, booting from USB didn't succeed here. I used an alternative method (placed the bootfiles on system disk, and the netinstall iso on usb).

Summary

Bluetooth doesn't work, which I saw noted with other HP laptops as well.
Wireless works with my G router. It has 50% connection, but tends to be rather slow here.
Touchpad works nicely here.
Keyboard works perfectly. All the hotkeys and Fn keys work as advertised.
I'm using the open source radeon driver with 3D enabled.
CPUfreqd works fine as well. Just as reading the battery status with ACPI.
Default action when the lid closes is to disable the screen. I haven't tried other ACPI options.

After 2 years of using Wifi, and often having problems, I finally started blaming the Wifi Chipset and the drivers. I could connect with some Access Points, and not with others, but the speed was always terrible.
The chipset is a Broadcom BCM4313 chipset, which should work under the opensource brcmsmac, or the closedsource wl driver. Both gave the same results.
I now switched to a Edimax Nano-USB chipset, a EW-7811 with a Realtek RTL8188 chipset, and it works wonderfully well.
