No improvement over patch v2 with patch v3. I haven't collected neither 
log nor regs dump though.

I started to poke at register manually after applying v2 the other day, 
but no luck. Is there any specific range of registers that are more 
likely than others to help ?

Would a picture of the distorted screen, together with a picture of how 
it should look like, help ? I don't know how to describe the distortion, 
a picture is worth a thousand word :-) The display is compressed in the 
top third or half of the screen, and diagonally stretched to the right. 
The remaining bottom part of the screen seems like uninitialized memory. 
It seems like the framebuffer is using a different horizontal resolution 
than the display. Could it be something like wrong "pitch" ?

Regards,
Xavier
