[Savage40] xe3 mode switch problems

[Alex Deucher]

Sorry, I can´t write much now or help you debug as I´m out of the
country at the moment, but there is a bug with screen to screen copies
as I recall in depth 24 on crtc2.  you can either disable that with the
noxaa... option or grab the latest version of the savage driver from
xorg cvs.  the code and binaries on my website are very out of date at
this point.  Depth 16 should work properly with full 2D accel in all
modes.  If you are still having problems, I can help you debug them
when I get back in town.
