Did you have the chance to test a kernel that includes the following
commit

"drm/nouveau/gpio: reimplement as nouveau_gpio.c, fixing a number of
issues"


It does rework the gpio handling and initialization (among other things), that 
should have positive effect on your issue 

It is part of linux 3.3rc1 [1] as well as nouveau linux tree [2]


Cheers
Emil
