The problem is already bisected. The commit that introduces the regression switches nv50 to use nvc0's disp implementation. The commit is basically deleting all the nv50 code and changing a few function pointers to use the nvc0 implementation. I tried pin pointing what the problem was (see comment 34) but I was not able to fix the problem.
