 That's likely because the filenames are wrong.

 The Cobalt PROM tries to load /boot/vmlinux.gz from the root partition.
Stick the disk back in your desktop, boot it with the rescue CD, and make
sure that file is there. I'd highly recommend using cobalt's kernel, as it
has support for the LCD panel, and more importantly rebooting.

 The difference is that cobalts don't use a boot loader, so you can't just
put a bzImage or vmlinuz file into /boot, tell lilo/grub where it is, and
hope for the best.

 I reiterate - make sure that vmlinux.gz is a gzipped version of the 2MB+
"vmlinux" file from the kernel RPM. Cobalt's RPM installs this file in
/boot for you, redhat's one leaves the uncompressed vmlinux file. Do not
just rename the "vmlinuz" file.
