 For what it's worth, I'm using an atapi cd-burner.  It's one of the
 Phillips cdrw800 series.  I've always used 'auto' as the disk types in
 BIOS, and my dmesg shows the burner as expected:
 
 	hades:~$ dmesg | grep acd0
 	acd0: CD-RW <PCRW804> at ata1-master PIO4
 
 Could be that this hardware combination is causing your troubles...
