I have a 2645 as well (it's a 600E), and I experience this as well. sadly,
I have no insight, since I haven't investigated--even with APM turned off,
the screen does go entirely black when I close the lid, so most of the
time I just do that.

I have this in my kernel file:
device pcm
options PNPBIOS
for
4.7-STABLE FreeBSD 4.7-STABLE #14: Wed Dec 18 07:53:23 PST 2002
there's no problems running, but there is a seemingly intractable bug in
the interaction of the sound driver and APM--if you suspend the system,
sound doesn't work when it wakes up. I asked freebsd-mobile@ and the
information (including from Warner Losh) was that the pcm driver is not
APM-aware, and I'm not sure if it's even possible to fix.
I also haven't had any luck running pcm/csa as loadable modules, although
other people did, so it's possible I gave up too soon.
I was going to suggest checking the archives, but I can't find the
threads. maybe you'd have better luck.
HTH,
chris
