After changing the mainboard, booting of several preexistent FC8-Installations fails: "No volume groups found". (kernel can not mount root-filesystem.) DVD-Rescue-Boot however is OK, volumegroups are found and root-filesystem is accessible. I've been searching quite a while for a solution.
Have you tried to rebuild your initrd from the rescue environment? It's possible that the new motherboard requires a different set of kernel modules to boot than the old one.
