I just want to add my experiences here as well, which are quite similar.
FreeBSD 8.1-RELEASE on i386 (not amd64 at the time), xorg 7.5, at the time the
latest NVidia driver for GTX-285M hardware, on a Clevo W870-CU laptop.  The
system worked fine, but when I added hald to the existing configuration, I'd get
a very nasty hang of the whole system when the X server exited.

Eventually, it was as simple as 1) with hald, hang  2) without hald, fine

I will investigate the links embedded in other emails I've seen recently, about
not allowing empty devices and other hacks that I seem to have needed in my
xorg.conf.  If something useful comes of that, I'll post more data.  Otherwise,
I'd just like to add that this behavior is not limited to ThinkPads or ATI
