I suggest you try my 2.2.14pre9 rev.7 (the kernel for iBooks & co.). I
made some changes & fixes for wallstreet as well. However, it appears
that the floppy driver is not very robust and you may still experience
some troubles with it (not directly related to the fact that the floppy
is in the media bay). The shutdown is a typical symptom of a crash on
PowerBooks. Sometimes, you end up in the debugger, sometimes, it just
shuts down (if there was communication with the PMU in progress when it
crashed, xmon won't always correctly take over, I don't know why yet).

I'll try to look into the floppy driver when I find sometimes, my todo
list is already quite full (if someone else plans to fix the floppy
driver, please tell me).
