Actually, that's one of the big advantages of the KMS based driver. It
*does* transparently pick the native resolution of the detected
output(s) and set up a high res console. You can provide boot options
to override it, but unlike intelfb, boot options aren't necessary to
get things working in the first place.

If you want to run X later, you'll need an updated xf86-video-intel
(preferably 2.9.x) or xf86-video-radeon driver as well, since code to
support the KMS interfaces landed only slightly before 2.6.29 came out
in the case of Intel.
