Ok, I pulled those from a RHEL3 VM. Looks like SLES11 is using a newer
2.6 kernel. The idea I was poking at was to get the CD in the VM to go
through the ide-cd layer and not the ata/scsi route. I had to do that
for my RHEL3 guest to get some consistency with the DVD -- similar to
the problem you are seeing.
