I usually look up this kind of stuff in something like the cvs log
output.

You mean getting the values into shape for the MC_{FB,AGP}_LOCATION
registers? Taking the above into consideration, they're doing the same.

Might not hurt to add those, but the 2D driver needs to set them up
correctly anyway, in particular for when it's not using the DRM.

Look, the 1.100.0 was a failed attempt to express the incompatibility,
but it didn't prevent non-GATOS 3D drivers from locking up the machine,
for example.
Again, the cause for the incompatibility has been removed in the 1.10.0
DRM, so it...

I mean the changes I have been describing for the GATOS 2D driver.

I think it makes no sense to merge stuff with the vanilla tree when
there's more up to date code in the 2.6 maintainer's tree, but maybe
that's just me...

That's what the DRM in DRI CVS is, unless I misunderstand you.
