This is xorg server 1.17.4 running on SunOS 5.11 pkgsrc i386, I'm trying to load ati6 (DRI1 driver maintained in pkgsrc) for a r5450 card along with my builtin mga200 on a SuperMicro mainboard.
(unfortunately my previous geforce card died, it worked fine with 'nv' and the nVidia replacement
needs 'nouveau' will have to wait a bit for KMS on my particular platform).

The ati card details:
> 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Cedar [Radeon HD 5000/6000/7350/8350 Series] (prog-if 00 [VGA controller])

> 	Memory at fe8c0000 (64-bit, non-prefetchable)

If I force vesa instead of radeon, then things are fine.

This seems to be the area indicated in the backtrace:

I must say that the screen size '270 x 203' is a bit weird...
Just a bit higher in the log I have:

Vesa is *really* slow... any ideas?
