But 9.1 LiveCD does boot and I can see the data once booted, so there must be a way to fix the boot loader on the drive to work. Good catch. The fix landed in stable not so long ago (http://svnweb.freebsd.org/base?view=revision&revision=255017) so you wouldn't find it in 9.2 either. Can you try this: gpart unset -a active ada0 -- Sphinx of black quartz, judge my vow.
