The kernel is 2.4.18-bf2.4.  It has ide-cd compiled in to the kernel 
(CONFIG_BLK_DEV_IDECD=y) and is the stock 2.4 kernel that comes with Debian. 
There is no /lib/modules/2.4.18-bf2.4/kernel/drivers/cdrom directory, I 
presume since the cd stuff *should be* compiled in.  Also, this same distro 
sees standard CD/RW drives on several other machines.  So it's an issue with 
the fact that it's a DVD drive, IMO.

Does anyone know if there are special drivers for DVD drives, as opposed to 
plain CD drives?
