devfs is deprecated and has some problems. udev is now the preferred 
method of userspace device handling for the 2.6.x series. See the below 
links for more info (warning: some have a Gentoo bent; it seems that 
Gentoo guys are at the forefront of this particular field):

I would also recommend moving away from Debian to basically anything 
else; Debian's release process is very slow and totally b0rked. As 
well, nearly every other distro has an answer to APT these days (most 
can use APT as well) so that's no longer a selling point for Debian. 
Personally, I would recommend Gentoo.

If you compiled in SCSI support and SCSI emulation, all you need is a 
boot-time parameter of ide-scsi. You can ignore the errors for modules 
not existing (any script expecting a module when you've compiled it in 
statically will give this same error).

As well, the later versions of cdrecord don't require SCSI emulation to 
make use of an ATA CD-R/RW drive anymore, so that's not necessary 
unless you actually have SCSI devices.
