I've a Lenovo T61 with the same graphics, AFAIU (Intel 965GM).

Usually xrandr works fine for me, but sometimes I get the same thing you
do: the external monitor thinks it is getting a signal, but shows a
black picture.  Restarting X.org helps.

Usually my monitor is connected during bootup, and then I keep
pluggin/unplugging external monitors and suspending/unsuspending it
randomly.  And it usually works fine.
