Right.

That's especially strange as Nigel's swsusp2 survives the suspend. Here's
how it looks currently on my system [1]:


				pmdisk	swsusp	swsusp2
intel-agp not loaded		OK	OK	OK
intel-agp loaded, not in use	(?)	reboot	OK
intel-agp in use		reboot	reboot	OK

I haven't used pmdisk for some time, so I might be not authoritative.

[1] 00:01.0 PCI bridge: Intel Corp. 82845 845 (Brookdale) Chipset AGP
Bridge (rev 04)

I'm willing to test anything you come up with.
Best regards,
