Stan,

I have a SCSI CD RW so I have not had to deal with an IDE CD RW.

I googled "cdrecord: No such file or directory. Cannot open '/dev/pg*'.
Cannot open SCSI driver."

Looks like you need to modify your boot loader either grub or lilo.
See the following two results of my google results. Hope this helps.

Also, please reply to the Ubuntu users email list so everyone
gets the benefit of the question, the discussion, and the potential
resolution.

I hope my response is of help and use.

After spending much time figuring out how to get cd writing to work on LFS,
I finally got it this morning. Here are 3 easy steps to spitting some
coasters. You probably just need step 2.

1. Make sure you have cdrtools installed, and have ide-scsi in your kernel.
2. Add this option to your bootloader
hdd(or hdc, or whatever your cdwriter is)=ide-scsi
3. If you use pure devfs like I do, link /dev/scsi/(a big list of
directorys I can't bother to remember)/generic to /dev/sg0. If you use
devfsd, good luck figuring out how to make it work if it doesn't.
4. Put a coaster in your mouth, and spit it out. There is no step 4.

Well, at least it SHOULD work. I haven't actually burnt a CD yet, but
cdrecord -scanbus says that it's working.

Thought it might need the "append hdc=ide-scsi" fix.  Sarge installed
with grub so I edited the /boot/menu.lst file with guidance from google
to look like...

title           Debian GNU/Linux, kernel 2.4.25-1-386
root            (hd0,0)
kernel          /vmlinuz-2.4.25-1-386 root=/dev/hda3 ro
hdc=ide-scsi
initrd          /initrd.img-2.4.25-1-386
savedefault
boot

Not positive that is correct, but it seems to have worked as I see the
following with dmesg:
scsi0 : SCSI host adapter emulation for IDE ATAPI devices
