But it looks like the preferred solution is leaving KMS working, and
instead disabling radeonfb, which apparently interferes with kms. The
bug reports and related threads indicate that you're supposed to disable
radeonfb with this command:

video=radeonfb:off 

only problem is I don't actually know where to put that...
