you are running out of video memory.
the mga driver needs frontbuffer, backbuffer, depthbuffer (16bit) and
reserves one screen for XAA.
thus you end up with ~400kb of texture memory which isnt enough ..
either reduce your resolution ( naa.. :> ) or take a look at
xc/programs/Xserver/hw/xfree86/drivers/mga/mga_storm.c:837 (?)
and change (pMga->FbMapSize - 4 * bufferSize) to something like
(pMga->FbMapSize - 3 * bufferSize) - bufferSize/2
ie half a screenbuffer for XAA.
but with 1.5mb texmem qf wont run nicely either :7
