Hi Nouveau folks,

I've been encountering some corruption on pixmaps for a while now, and 
it seems like the problem comes from the DFS/UTS (Download From Screen / 
Upload To Screen).

In fact, I'm pretty sure the problem comes from there as screenshots are 
garbled and so does a few more things.

I may have time to dig this up, where should I start, is there some 
documentation on the NVS 140M ? Where is the gart2vram code located ?
Do you have any idea of where could be the problem ?

Thanks,

Martin
