kernel FPU trap panic

["John D. Baker" <jdbaker%mylinuxisp.com@localhost>]

While building packages on my PowerBook G4 667MHz (TiBook), the ssh
session became unresponsive.  The lid was closed, so I couldn't see
any display and when opened, the backlight was not turned back on.

Following forced reboot (Ctrl-Cmd-Pwr), the following messages remained
in the message buffer and were saved "dmesg.boot":

I don't really know how long it had been sitting there like this, so
There's likely no telling where the problem occurred.  It would seem to
be well off in the weeds at this point.
