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.

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
initrd          /initrd.img-2.4.25-1-386

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
