Can you say a bit more about this?  When I suspend, the panel dims,
but I can still read what's on the screen.  When I resume it never
brightens, but I can still easily see what's there.  I never goes
completely black.

If I boot up into linux using a text console, it displays similar
behaviour, dimming on suspend, but it brightens back up on resume.

I *have* managed to get it to go completely black using a horribly
hacked up version of acpi_video w/ the DPMS patches, but it still
won't wake up.
