Unfortunately, Linux needs the ability to support proprietary drivers...

NVidia drivers anyone?
At least the NVidia drivers rock.

  Yeah.  Agreed.  I have never seen a PC using an open source bios.

The SD drivers in the kernel are painfully slow.  I've used them on
x86-64 - plugging a SD card into a Dell 24" monitor with USB - the SD
card runs at about 30 kilobytes per second.  Its totally useless.
