Note that the register dumping tool doesn't capture everything. If you
really want to do some detective work you could dump the whole MMIO
space and compare differences. You should be able to find definitions
for many of the reg offsets in the docs at intellinuxgraphics.org,
maybe there's something we don't dump that's changing and that explains
your power consumption changes.
