Morgoth, could you make sure you use latest openchrome SVN, add
Option "PrintVGARegs" to your Xorg.conf, post your compressed xorg.conf at
the wiki logFiles file gallery.

Then it would be helpful if you could also upload a couple of compressed
Xorg logs for startups with and without VBEModes, and for at least two
different resolutions. (at least 4 logs).


DRI works *almost* fine. glxgears works with quite good result around

These are common errors when using a fast processor, but they tend to go
away when the hardware is feeling well. AGP DMA is still a bit shaky but I
hope to get some hints from a guy familiar with the hardware. Until then,
don't use EnableAGPDMA.

Strange. Xv should refuse to start with your chipset, or did you disable
the check?

I'll have a look at the DRM.
Thanks.
