Dell Precision M90 laptop workstation:

The processor is not recognised, but runs, and is correctly shown as two cores.
The video card - the OpenGL version of the G71 core as used on 7900GTX - is not recognised, shown as an 'unknown device 029a', but runs at native resolution and full color depth. Adding the NVIDIA-supplied binary driver enables full OpenGL support which works well.

The Ricoh SD/MMC/MemoryStick/xD reader is partially recognised.

I have not tried the IEE1394 port or the smart card reader.
Sound works, burning DVD works.
