I have the same problem, kinda sorta.  Closing the lid causes it to go to 
sleep in the context that a vetrinarian uses.  ("It was put to sleep.")

Wakeup just spins the drive. And spins. And spins. And spins.

The machine is also a 64bit.  HP zv5200z AMD64 3700+.

According to a friend, 32bit suspend works in 32 bit but not 64bit.
