Thanks to schlobinuxes help in IRC, I've got 1080p to work via HDMI.
You need to use openchrome-drm from git (so essentially, you have to
build the whole kernel unless you're already running some Linux 3.9
RC). 1080p also works with KMS enabled (via.modeset=1 in cmdline), but
with KMS enabled, there's no XV support and (as schloblinux explained)
just very little 2D acceleration (it's fast enough for "standard office
work" though).

Thanks for the great efforts all of you are putting into this driver
anyhow. You folks are terrific! :)
