The problem is still present in hardy, all -updates. The setting Option "NvAGP" "1" is still required to wake up from hibernation. Observations:

- Different nvidia drivers are alike - all need the setting.

- The problem is present in Kubuntu and Ubuntu, also in a fresh install.

- The problem is present with two different cards: MX400 and Geforce 6200.

- In xorg.conf, Option "NvAGP" "1" must be present - NOT Option "NvAGP" "True". I can't explain it, it's very weird.

- I get "NVRM: not using NVAGP, an AGPGART backend is loaded!" in dmesg when setting this. STILL the setting is required (Xorg.log has "Use of NVIDIA internal AGP requested"). This is weird, I can't explain it.

- When NvAGP is set to "1", other quirks in acpi-default or elsewhere are not required - hibernation just works.

- This is a VIA chipset in a desktop laptop (not laptop). Most likely, this problem is a related to some VIA bug. "dmesg | grep -i agp" yields:

[ 35.054019] Linux agpgart interface v0.102
