Yeah, same problem with all Lucid versions up to Beta 1 now. I also have a separate /boot partition (ext2), karmic on /dev/sda5 and and lucid on /dev/sda8 . Whenever I update grub.cfg via some kernel update in Lucid, Lucids's UUID is written to all entries in grub.cfg which makes Karmic not bootable any more. I manually have to revert the changes. Seems to be similar to bug 392836 or bug 462961, but they're marked as fixed...
