I just tried it on a Dell Precision M4400 (Core(TM)2 Duo CPU T9600),

FreeBSD localhost 10.0-CURRENT FreeBSD 10.0-CURRENT #556 235262M: Fri May 11 06:07:31 EDT 2012     root at localhost:/usr/obj/usr/src/sys/CANARY  i386

(Writing from BSDCan; home mail machine seems wedged.)

It seems to work for me -- I was able to use the keyboard (Fn+F1)
to suspend; once I closed the lid, the power light visible on the
outside would blink slowly (about a 0.5Hz cycle time w/ 50% duty
cycle, estimated); when I opened the lid, the machine resumed
"automagically".  I tried it first merely from a vty, then from X
(nVidia driver, updated as of this morning).

I'll try stable/9 & stable/8 as time permits.

Thanks! :-)
