Comment(by Quozl):

 unable to reproduce any unexpected delay on 2.6.31

 the delay i'm getting is purely syncing filesystems.

 from virtual terminal text console on laptop
 dmesg -n 8
 echo mem > /sys/power/state

 the interval is 4 to 6 seconds betweeen
 PM: Syncing filesystems ... done.

 PM: Preparing system for mem sleep
 rtcwake includes a call to sync which repeats the same delay.
