2.4.3-ac3: Oops while insmoding BusLogic over ide-scsi

[Eric Buddington]

2.4.3-ac3 on a K6-2, kernel compiled with gcc-3.0

The following oops occurred after the following sequence:
	modprobe BusLogic
	rmmod ide-cd
	modprobe ide-scsi -> shows up in proc, but not as /dev/scsi/host1!
	rmmod BusLogic
	insmod BusLogic -> Oops!

And lsmod tells me:
	BusLogic               82976 (initializing)

Time to reboot...
