Incidentally, if you want to be *sure* you capture all panic output,
you might consider putting a comconsole into your kernel and hooking a
serial terminal with scrollback and/or logging (old PC running kermit
works fine) up to be the console. Then, no matter what gets written,
or not written, before the machine freaks out, and before fsck
"cleans" everything, you have it all logged on a separate machine.

Out of curiosity, do you have "options DIAGNOSTIC" in your kernel? If
so, remove it, rebuild, reinstall.
