I have this exact same 'issue' with almost the same hardware.  As far
as I can tell, when the ide-scsi module is loaded, it takes control of
all non-harddisk IDE devices on the system.  I think there's a work
around, but I can't for the life of me remember it.  If it doesn't
bother you, I'd just leave it.

Oh yeah, there were a couple of other things, (all good:):
* You can use tools like jazip (for your zip drive) that only
  understand SCSI.
* Apparently some cd-rom drives can perform DAE (digital audio
  extraction, ie rip) cds quicker with ide-scsi enabled!


I did not vote for the Australian government.
