output of "avivotools regs" with kms enabled

When booting the system with KMS enabled, the screen is stuck in 1280x1024 at 60,
even though dmesg (and xrandr in X) say that the active mode is 1920x1200. The
area available in X is indeed 1920x1200 (programs occupy the usual space) but
it is scaled (and stretched) to fit into 1280x1024.

Changing the resolution via xrandr influences the space available to programs
while the resolution remains the same.
