Well, I got it working with SuSE's kernel version 2.6.5-7.111.19-smp, but that doesn't explain to me why I can't make it work with a stock 2.6.10 kernel. Now I'm hitting the "kernel madness" which broke CD/DVD burning for all but the root user.
I believe it was 2.6.8+ that changed the way cd burning (SCSI generic or ATAPI SG_IO) support worked. This was done to fix some security issues where a user could e.g. reflash the firmware on your drives, rendering them toasters. There is now some SCSI command filtering done to prevent such things. Fedora has pretty much abandoned ide-scsi and has switched instead to the SG_IO API directly on the underlying ATAPI device. This allows applications to send SCSI Generic commands by using the ATAPI device instead of the SG device which required the ide-scsi hack for ATAPI devices. I know this change broke a lot of things, mainly people's expectations on which device to use with cdrecord et al. It is now as simple as: cdrecord dev=/dev/hdc or similar.
