linux-pmac 2.2.10: media bay panics on PBG3

Hi!

	At last, I managed to upgrade my PB G3 to linux-pmac 2.2.10.  Sound works
definitely better, and my 3-button Contour mouse is recognised.  However,
removing the floppy drive from the right media bay and inserting the cd-rom
results in a kernel panic:

[media bay contains the floppy drive, which is now replaced by the cd drive]
media bay 0 is empty
media bay 0 contains a CD-ROM drive

Any idea how I could fix this?  Because of the mouse support, I would prefer to
stay wit 2.2.10.

Thanks, Albrecht.
