Connor, first, thanks a lot for caring for these old drivers. A lot of
people are still using their old laptops and run the latest Linux
distributions on them.

Thanks especially for the hint you gave earlier in this thread: "EXA
callbacks that use the devPrivate.ptr of a pixmap." I am trying to
keep the savage driver working, but I don't have the capacity to
follow xorg development in detail. Recently an EXA problem came up for
which I had no clue. Reading your hint was enough to guide me in the
right direction and now I believe I have fixed it with a one-liner

Pander, does console switching work with the vesa driver? It doesn't
on my savage card, so I wonder if it is a more general non-KMS
problem. You say it works with the older SiS driver though, was that
also on the latest xserver?
