I've wasted a lot of time with the mmio registers to find out why things go
slow. But it seems it's something else.

Just loading the nvidia kernel module without starting X is enough to make
nouveau go fast after kexec.

I did an mmio trace while loading the module, but it only wrote 140 to 0, and
that was all. I've checked the PCI config space, also nothing interesting.

Any tips how to find out what happens?
