dselect won't read CD's

[Abyss]

I'm building a 2.2.15 kernel with potato (I386) and, on boot up, I can 
mount /cdrom with no problems and can access files on it.  However, dselect 
won't recognize the Debian I386 install CD's.  If I reboot with the old 
kernel 2.0.36, everything works fine.  Same CD's.

In the 2.2.15 kernel, I've included IDE-ATAPI, ISO9660, Microsoft Jouliet 
Extensions and tried various other combinations but can't seem to get it to go.

Any ideas?
Thanks.
