I missed it - I only subscribed yesterday, and while I did take a look at
the archives, I didn't look _that_ closely.

Anyway, merging tends to be fairly easy to the 2.5.x tree, because if
something breaks it's not a huge deal. The 2.4.x tree is a lot less
forgiving.

The way I merged was to just do a unified diff between the two trees, and
hand-edit the diff by hand where required. Not many edits were necessary,
since most of the DRI kernel tree seems to have been really just cleanups
(dropping support for pre-2.4 kernels, yay!).

And apparently some work had already been done on 2.5.x integration, as
many of the 2.5.x VM cleanups had already been worked on (ie the
"vmalloc_to_page()" stuff). The things I had to drop were some minor page
table handling stuff and some chipset names where DRM seemed to be behind.

Oh, and the 2.5.x kernel Makefiles have been much simplified, so I did
that merge by hand. But I only have ATI cards here, so I've not tested the
result very well..
