MacBook screen very dark after resuming on OS X 10.8

                          I have a MacBook late 2008 aluminum model (5,1).  Occasionally, after reopening my MacBook's lid, the screen doesn't light up.  With effort I can see that the password prompt is actually rendered very faintly on the screen.  *Very briefly*, for a split second, the screen does seem to flash on before going dark (consistently).

I tried closing and reopening the lid multiple times and changing the brightness, but no luck.  The only way I know of getting out of this is to hold the power button and do a hard reboot.

This started happening after doing a clean reinstall of OS X 10.8.  I upgraded very recently from 10.5, where I never encountered this issue.

I'm pasting below the relevant time slice from my system.log (which involved several iterations of closing/reopening the lid) - I didn't notice anything helpful here.
