All,
I have a Macbook Pro 13" (mid 2009) that has had a long time issues which seems to be getting worse.
Occasionally, I will go to wake the computer with the keyboard and can't wake it. The HDD spins up, the light on the front of the computer stops blinking, but as soon as it seems like the display should light up, the HDD stops and the light begins blinking again.
More rarely, the computer will suddenly sleep while I am using it and then enters the same sleep loop.
The only way to resume working on the computer is to wait. Doing a hard restart just puts it right back into the 'sleep loop.'
Here is an excerpt from kernel.log showing the laptops apparent narcolepsy:

I have tried reseting the SMC and reinstalling Lion (short of erasing and installing) to no avail. The Genius bar has insisted that the problem would be resolved by reinstalling Lion (which they did, but didn't fix anything, still insisting...).
Please don't say "logic board." Thoughts?
