Hmmm. Actually, the writer is IDE/ATAPI with SCSI emulation via the ide-scsi module. The drive is detected just as the normal ATAPI CDROM on my system is.
I have now managed to get two CDs burned without difficulty (not too loud or it will jinx it) but set the speed to 1x instead of 2x. I will also try eliminating the "devfs=" statement in lilo.conf on someone else's suggestion (buggy?).
