Hi Dario, With the help of Sergey Zharkov I narrowed down the problem. I'm CCing this to the dri-devel and savage40 lists as a summary.
The problem seems to be in the AGP GART driver which is in the Linux kernel. A new snapshot won't help you, I can't fix the problem there. I haven't had the time to prepare a good bug-report for the kernel developers yet. I would have to upgrade the kernel and get swsusp to work with it first (last time I tried this was several months ago). I think I won't have time for this in the next two weeks. :( See my comment below for a good workaround.

This will disable any use of AGP memory, both for textures and for DMA. With BusType "PCI" you do not need to set DmaMode to "None", but you may get slightly better performance.
