I think i saw something similar too, but in last few days suspend/resume 
worked fine.

One reason could be that the phone wakes because of signal strength change. Do 
you disable signal strength modem reports before suspend? I always send 
"AT_OSQI=0" before suspend.

Another thing is that i use QtMoko's feature which suspends phone after 20s 
when screen is locked, so it can save power on random wakeups.

In QtMoko it works same as Freerunner. But the suspend-when-locked feature is 
similar. I am personally using this featuer since Freerunner.
