I narrowed down the 'blinkage' issue to commit "drm/nouveau: allow entire
0x0002xxxx range in VBIOS parser on >=nv50",
http://cgit.freedesktop.org/nouveau/linux-2.6/commit/?id=66125505c3ac0e201e8286c777be46f3b415ff53,
this is what makes my NVA0 go crazy. I'm really happy that it all went well, my
first time git bisecting anything...For each nouveau.ko that I build I had to
hexedit the vermagic section/symbol to be able to insert the module into the
current running kernel since vergmagic was always different after every compile
(and I had to end with same filesize otherwise it wouldn't load!?). Is there a
better way to do it? From what I read there's other way to do, e.g. strip
.modinfo symbol but this never worked for me (objcopy -N .modinfo mod.ko
mod-stripped.ko)

stillunknown, AFAIK the fuzzy screen was a result of blinkage. Also the
exapixmaps/tiles work for me now. There was at least 1 other person on the IRC
that described similar blinking issue, I will try to make a video of what I was
experiencing ;).
