I'm just coming into this, but it seems like the i810 driver is getting 
confused between new (ie ttm) and legacy drivers - you are being 
directed to use the legacy driver, but the memory looks like its being 
set up for the ttm driver.

The ttm driver allocates its own memory for textures and doesn't use the 
fixed region set up by the i810 driver.

I'm cc'ing Thomas in case he has an idea about a fix.
