The display on the 5480 starts about 48 pixels too low. ie: the entire
screen is displayed too low. Hardware features like bitblit etc are
starting at the right place, but draws are too low. Using "noaccel"
allows window dragging etc to work ok, as they will start at the wrong
offset as well.
Running at 1152x864 results in an additional horizontal offset.
swcursor stops in the offset location and disappears off the bottom
hwcursor is garbled, but appears to be in the correct x/y position.

The cirrus 5480 is built in to the main board and appears to share
system ram.
XF86Config-4, log and other info on http://Rikers.org/l440gx/
If I remove the voodoo3 card, the cirrus starts up correctly. Changing
the MemCFG1 and MemCFG2 seems to have no effect.
Thoughts?
