I got also a kernel panic on 2.6.20-9 in a Kubuntu Feisty Herd 4++ on a MacBook Pro Code 2 Duo. 2.6.20-8 works fine.
The message is something like this:
[...] [numbers] message... [numbers] message... [numbers] start-kernel +... [numbers] uknown_bootoption [17.084000] EIP: [<c0116a65c>] __get_um_area_node +0x10c10x100 SS:ESP 0068:C03cddb4 [17.084000] <0>Kernel panic - not syncing: Fatal exception in interrupt
