This almost certainly means the kernel or initrd didn't load properly.  The
filesystem on / is a red herring; it'd say different stuff starting with
"Linux kernel 2.6.9-78el4 blah blah..." if the kernel loaded right.  Check
the grub.conf stanza, make sure its kernel and initrd lines don't have any
tyops in them.  Also that both the kernel and initrd files are fine (have 
the same md5sums as their sources, etc.)

ext23 is backwards combatible to an insane degree, and my own adventures with
custom kernels make me think you'd see screenfuls of boot messages before the
"kernel panic: cannot mount / on 08:03" if it were a filesystem thing.
