when I went to /boot and did a mkinitrd, I saw the new boot images and
figured it out. Obviously the entries were in grub.conf too.

In my case, that wasn't entirely helpful because I have to do the
mkinitrd stuff for the old megaraid driver and I probably should just
get the kernel code for the appletalk module and make the appletalk and
megaraid modules for each new kernel myself

Anyway, I 'hope' that I don't have to rebuild megaraid.ko that I
compiled with 2.6.9-11.ELsmp for 2.6.9-11.106.unsupportedsmp as that
would double the effort. I will know soon enough. I am about to put the
new floppy drive into this case, button it all back up and start it up
again.

Thanks for all your efforts - the 'unsupported' in centosplus was a very
nice touch. Considering that and the i586 support, you guys seem to go
the extra mile.
