Actually, I guessed on my own, and this solves it:
append="hdc=ide-scsi hdd=ide-cd" in lilo.conf
In rc.modules:
/sbin/modprobe ide-scsi /sbin/modprobe ide-cd
Gives this in dmesg:
SCSI subsystem driver Revision: 1.00 scsi0 : SCSI host adapter emulation for IDE ATAPI devices Vendor: HP Model: CD-Writer+ 9100 Rev: 1.0c Type: CD-ROM ANSI SCSI revision: 02 hdd: ATAPI 40X DVD-ROM drive, 256kB Cache, UDMA(33)
I don't actually know if the hdd=ide-cd does anything for the ide-cd module, other than keep the ide-scsi module from grabbing it. Conversely, the ide-cd module only grabs hdd even when the ide-scsi module is not loaded (making hdc free). So it appears to do something.
As it turns out, the latest version of cdrtools (2.0) supports ATAPI drives directly. I tested this by burning an ISO, reading it back, and comparing the md5sums. So the whole ide-scsi exersice looks to be academic at this point.
Have fun,
