Unhappy Resume from Suspend Failure : Ubuntu 9.04, PNY GeForce 6200 AGP

I am having some issues getting resume from suspend to work with my configuration, and I'd appreciate some assistance.

I have an ASUS K8V SE Deluxe mobo. The system seems to be responding nicely with everything except the video card. If I boot with the test_suspend=standby option, everything behaves correctly. I can also do standby (S1) successfully from X and resume. The problem is with S3 (suspend to ram). If I boot with test_suspend=mem, the system suspends to ram correctly, but when it resumes, I get no video back. I can intereact blindly with the machine well, and I always have a network connection after boot.

Similarly, I can 'echo mem > /sys/power/state' and resume (again without video). See the dmesg log below.

running 'vbetool post' consumes 100% CPU and never completes. Similarly, enabling the 're-POST video card after S3 resume' option in my bios causes the system to hang after resume.

I saw information that some NV cards don't resume from suspend well unless X is handling the resume and using NVAGP. I have not been able to get NVAGP to work because it doens't seem possible to disable GART_IOMMU on newer x86_64 kernels (see: http://www.nvnews.net/vbulletin/show....php?p=1992566).

I have enabled PM_DEBUG and ACPI_DEBUG, but nothing "useful" pops out in dmesg:
