Notes
Tested with archlinux.
Suspend does not work out of the box due to problems with the usb buses, they need to be disabled before going to sleep.

Passing pcie_aspm=force i915.i915_enable_rc6=1 to the kernel (3.0) will decrease power consumption.
The NVIDIA card is possible to turn off using acpi_call but this is considered highly experimental at the moment (may mess up your BIOS) but it seems to work for me (use at your own risk).
Summary
This laptop runs quite well with linux, but tweaks are needed to get the power consumption down and suspend to work.
