Debugging output still does not help me understand much... but nevertheless I
wanted to give it a try. 

The first problem with the patch was: I don't have the file "nv10_gpio.c". Is
that a problem? Ok, I guess I should be using latest nouveau git instead of a
stable kernel anyway... so I tried the out-of-tree build (alternative), but
there was a new problem:

In file included from
/usr/src/nouveau/master/drivers/gpu/drm/nouveau/nouveau_bios.c:31:
include/linux/io-mapping.h:25:23: error: asm/iomap.h: No such file or directory
make[3]: *** [/usr/src/nouveau/master/drivers/gpu/drm/nouveau/nouveau_bios.o]
Error 1
make[2]: *** [/usr/src/nouveau/master/drivers/gpu/drm/nouveau] Error 2
make[1]: *** [_module_/usr/src/nouveau/master/drivers/gpu/drm] Error 2
make[1]: Leaving directory `/usr/src/linux-source-2.6.35'
make: *** [modules] Error 2

I suppose it is an architecture-related problem. In kernel 2.6.35
nouveau_bios.c does not include "linux/io-mapping.h" yet, so "asm/iomap.h" is
not required either. The later file is in
"linux-source-2.6.35/arch/x86/include/asm/iomap.h" on my system, whis is
probably not good for a PPC. There is also a
"linux-source-2.6.35/include/asm-generic/iomap.h", which might be an
alternative.
