FreeBSD 5.3 on Thinkpad X40

[Khairil Yusof]

Has anybody gotten FreeBSD 5.3 to run ok on a Thinkpad X40?

Whenever I press any of the display keys (brightness, led light), volume
buttons, or the lcd is turned off either via folding lid or dpms, it
results in a freeze (both X or console).

I've tried disabling acpi and apic, but I can reproduce the lockup by
doing any of the above, even with them disabled. Removing power cord
also locks up the system.

Right now, I can do without any form of suspend features, as long as I
can just close the lid, or blank the lcd screen without locking up the
system.

Being a laptop newbie, some advice on where to start in tracking the
down the problem would be much appreciated.
