Default Re: 9629 driver and modelines

I'm pretty sure I'm having the same issue.

I've got a Sony XBR1 TV hooked via DVI->HDMI from a GeForce 6800 on the 9620 driver and Ubuntu Edgy. I've got a custom modeline that underscan's just right and worked fine on the previous driver (8776).

What it looks like is for some reason the driver is no longer seeing custom modelines, as if Option "ModeValidation" "NoXServerModes" was persistently turned on or something like that. Unfortunately because HDTV's are flaky I need that bizarre ATSC720 custom modeline if I want to not have any overscan. I'd use the older drivers but I had trouble with them and Beryl working correctly
