I think I have the same problem. My system seems to swap everything in after resume from S3 sleep.

Even though this is marked as a duplicate, I think this is possibly unrelated. I am using the fglrx module. This is on Jaunty, with an Asus F6V. 

I see this in the dmesg on the machine:

Using the latest kernel:

shane@shane-asus-laptop:~$ uname -a
Linux shane-asus-laptop 2.6.28-15-generic #49-Ubuntu SMP Tue Aug 18 19:25:34 UTC 2009 x86_64 GNU/Linux

I'm going to try this without the tainted drivers and see what happens.
