ACPI seems fatal error on my T41

[Jiasheng Hao]

I install FreeBSD on my new T41 2373-9FC, and all
works wonderful.
But I find some problem:

1. sleep/suspend/resume dosnot work at all;
2. closing the lid or pressing any special key(such as
volume control, fn+f3, etc)
   will make the machine hung, staying there with no
repsonse any more;
3. started with acpi disabled or safe mode or single,
system will hung just one or
   two minites;
4. if started normally with acpi enabled, and not
typeing any special keys, system
   work wonderfully, and fan seems work correctly too.
But it will not sleep.

I cannot set hw.acpi.osname to ``Windows 2001''. Any
suggestion or help would be
very appreciated. Some of my infomation goes like
these:
