Well... this is a _compile_ fix... ;)
But when you boot a kernel with this patch... it hangs directly after SCSI subsystem driver Revision: X.YZ

This does not boot, as idescsi_init seems is also called by the scsi subsystem. The following patch actually boots on my system:

This patch does not work too....
Only one ide-scsi device will get detected
BTW: why do I get an oops (reported 2 or 3 times but no answers) when mounting cdroms since 2.5.7 or something?

Yes indeed, I should have tested it first 8-(.
New patch sended to the list, this one actually boots:

Because the ide-scsi code hasn't caught up to Martin's IDE cleanup changes yet.

That's not the case. The problem is simply the SCSI part of the game, (80% of certainlity) which seems to don't deal properly with hot pluggable drives right now.
