lspci -vnnxx

Sapphire Radeon HD3850 AGP card on nforce2 mobo.

Been testing kms and until 4aac047323e3082d0866b8ad3784236632105af4 it worked
OK (barring nits) for me doing modprobe radeon modeset=1 agpmode=-1. Current
git also works with that reverted.

Without revert I get a ring test fail with agpmode=-1.

It has always failed ringtest and oops without agpmode=-1.

Attached are 

lspci -vnnxx

dmesg failing with current git and agpmode=-1

dmesg working current with revert.

dmesg showing agp fail + oops
