You could re-compile the kernel under FC-1 with aic7xxx in the kernel
rather than a module.
(I'm assuming FC-1 and FC-2 look for /boot in the same place.
If not, copy or move the new kernel, initrd and System.map
to the appropriate place.)

Nb Are you sure you have the correct entries in /etc/grub.conf
and /etc/fstab ?
I'd replace any LABEL= by the actual device /dev/hda5 or whatever.
