Nice, thanks. But what's the problem with the stride?
The only way the stride in DGA modes is going to change is if you
restart the X-server and change either colordepth or the virtual
x-size of the display.

Yeah, I probably did. That was one of the last things I coded,
around 0430 in the morning or so. Actually I even remember pasting in 
(GT_SIZE(mode->graphtype)+7)/8*mode->virt.x and manually changing
it to virt.y. Must have been really tired. ;-)
