Insight from an XFree86 developer on the Millenium TV shift bug (wrong
DGA address for visible start of frame buffer). Sounds like XFree86 4.0
and pre-releases (DGA 2.0) is the route to go. So test out those pre-releases!

[XFree86] 3.3.5 won't have that problem for cards that don't have WRAM.
The problems with the old DGA is it didn't make the distinction between the
start of the framebuffer and the start of the visible part of the
framebuffer. For the WRAM cards, these are not the same for modes using
more than 4 Meg of ram. Prior to 3.3.5, this was erroneously being done
for non-WRAM cards as well. DGA 2.0 is the only way to remedy this problem
for the Millennium and Millennium II.
