James' scsi tree already contains an big update to wd33c93 that will make
integrating pc980155 a lot easier - it will hopefully appear in 2.5.63.

I've done some more work on the bios parameter stuff, this is the patch
I came up with, James can you merge it into the linux-scsi tree?  It just
adds a new file for pc98-style bios geometry to the scsi core.
