Can I have 250MB gfx mem +6MB shared PCI mem?
According to another thread I've been in, the 128MB issue is due to the way the Radeon 92xx's memory banks are set up. Instead of one bank of 256mb, it's in two different 128mb banks.
With the Mediator drivers, you'd need to specify the Radeon Memory in the ENV-Arc:Mediator:RadeonMem file to be 15 (for full on resolutions, I don't think any resolution really uses more than that) and then use AddMem to add the second bank of Memory. I think I had it working at one point, but then reinstalled, and didn't get it working since... gonna have to reinstall again, since I think something got corrupted along the way

I keep having stupid lockups in all Radeon resolutions.
Just haven't had the time (or focus) to be able to do it. Probably will this coming weekend.
But I'm wondering if using this OpenPCI driver will work better...
