For video.  Does any one support anything else?  RAID cards?

Yes, there are reasons it is unlikely to happen and those are reasons I
really have not done much.  Stefan believes in it so I think it makes a good
test case of what we can support in LinuxBIOS.  Mostly this is if I had
to support the interface it would not suck to support :)

What I am actually thinking is the long term solution is to just use everyones
driver disks (or the equivalent) for linux and if the BIOS does not contain
the drivers you need it is just a rebuild of your boot loader away.  Yes
this means you have to boot your system once to load the driver for your
new cool boot device but that should always be possible.
