freebsd stable - Oct 2005 - Could NOT get X to work at IBM thinkpad i series 1300

I followed the instruction but i can not start X, the screen is black
and the laptop does not respond user, only a reboot through ssh can
save it.

I installed Freebsd at my Dell laptop and it works well, and I
installed Debian linux at the same IBM thinkpad, it works well. but
just can not get freebsd to wrok.

the laptop is IBM thinkpad iSeries 1300. This unit has
a silicon motion LynxEM+ video chip and a 800x600 display.

here is the log file:

At this point the screen is black and the laptop does not respond the user,
