Quite frankly, is there any major downside to just disabling/removing
intel_bus.c for 2.6.33? If we're not planning on having it in the long run
anyway - or even if we are, but we can't be really happy about the state
of it as it would be in 2.6.33, not using it at all seems to be the
smaller headache.

The machines that it helps are also the machines where you can fix things
up with 'use_csr', no? And they are pretty rare, and they didn't use to
work without that use_csr in 2.6.32 either, so it's not even a regression.

Am I missing something?
