Registers should be aligned to 0x4, otherwise bad things may happen depending
on the motherboard chipset

The register mentioned is "off by one" to NV_PCRTC_GPIO_EXT (0x0060081c).
Whenever nouveau detects a misaligned register, we strip and align it before
accessing it

The bug mentioned is very unlikely to be related to the misaligned registers in
the vbios, as the register in question does handle the crtc gpio (display
controller)

Feel free to take a look at nouveau_bios.c: valid_reg() and bios_rd32()
There are some hints that may help us out and get rid of those annoying
messages


Appreciated
