DPMS broken in xfree 4.x/gnome 1.4?

[Rick Macdonald <rickmacd@home.com>]

On 3 different machines, DPMS no longer turns off my monitors after
upgrading to woody/sid/XFree86 4.x/gnome 1.4. The screen goes blank, but
it doesn't do the suspend/off.

I suppose it could be a problem with gnome 1.4 since that was installed at
the same time, but even "xset dpms force off" only blanks the screen but
still doesn't cause the monitor to go into power-saving mode.

On one machine, the problem carried over after switching from an ATI to an
Asus GeForce2 (nvidia) card (just using the "nv" driver for now).

Any ideas?
