The parameters you entered for your kernel (original post) don't look
right to me, especially root=/dev/sr0. That alone could account for the
kernel panic.

When I boot the kernel designed for Suse setup (as shown above), I clearly
see "loading USB" support. If your CD is supported and you have Suse
setup CD1 in the drive, setup will begin.
