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.
