OK, we tested and memory is correctly uploaded. Also did a dump of pushbuffers,
and nouveau does set the address of code to execute correctly.

Yet, for some damn reason GPU still executes from undefined location.

OK, we mmiotraced the blob, extracted ctxvals/ctxprog, and yes, problem
disappeared. Also it was noted that some graphical corruptions disappeared.

So, folks we really need better coverage of ctxprog and especially ctxvals,
because these seems to contain chipset revision specific workarounds....

Could we allow to load ctxprog/vals of nvidia then? so that users could do that
in easier way that patch their kernel?
