Keyboard induced sleep did not solve my problem.
Do you happen to use the "new" desktop effects? I cannot prove it yet,
but it seems that once I turned the effects off, the laptop wakes up
from sleep as it should. I will give it few more days to see if this is
indeed the problem before I file a bug report. If it is, then it maybe
a problem with X Windows or the nvidia driver.
