rv530 AGP + nvidia-agp Problems

[Andy Furniss]

Hi

I've been trying to get my Sapphire X1600pro AGP to work with the latest 
  git ati/drm on an nforce-2 mobo and have a few problems.

I have new drm/radeon .ko from git in /lib/modules.. and git/module/..

If I don't modprobe nvidia-agp then X starts and functions OK until I 
try and use xv - I then get a hard lockup (have tried specifying ports 
with mplayer).

Log (attached - log-xorg-no-nvid) shows AGP not initialising correctly 
though drm,agpgart and radeon modules are autoloaded.

If I first modprobe nvidia-agp then X fails to start, though the box is 
still up.

Log (log-xorg-nvid-loaded) shows some warnings and is truncated, kernel 
log ends with a r300 microcode message.

xorg.config is almost empty - just a keyboard section.

I am not subscribed to the list.
