Well you are lucky then :) 

Yeah X 'worked' but it worked as slow as with vesa video driver here.

Also starting something like supertuxkart made it crash or I got a black screen :(

The only game I managed to start ( without X to crash ) without that patch was supertux but is was slow as hell.
However I'm not a gamer but I need X to work right.
