Unichrome Pro (K8N800/Mitac 8889 chipset) hangs up the computer when handling
textures. The bug can be seen almost in any OpenGL game (I've tested PPracer,
Trigger, Torcs, FlightGear, AlephOne). Sometimes, you are able to start the game
(maybe after some tweaking in resolution, bpp, fulscreen mode, etc) but after
some minutes it hangs up and you need to press Power button on your computer.

Steps to reproduce (using Trigger as example):
1. Download Trigger from (http://www.positro.net/trigger/) and install it
2. Choose Single Race->Far, far, away->Start Race from the game menu.

Expected result:
You should see an outline of the car rotating and be able to choose another car
by pressing cursor keys.

Actual result:
The computer hangs and you need to press Power button.

I've did some debugging and found that 3D driver apparently doesn't like
GL_LINEAR_MIPMAP_LINEAR texture parameter. A trivial workaround for via_state.c
(which makes Trigger 0.5.1c to work) is attached. However, this does not solve
the problem completely: FlightGear anf Torcs (and probably other games I have'nt
tested) are still locking up my machine.
