That works here, I can do 800x600 and 640x480 on my 1024x768 panel.
Also, the output refactoring seems to have fixed xrandr --auto; before
I had to manually move the LVDS to crtc 1 if I wanted a non-clone
setup, since only crtc 0 can drive the VGA output apparently.

There's one cosmetic fix that I've attached: report the ivch as
connected if we've managed to talk to it.  Right now the ivch backend
always reports XF86OutputStatusUnknown, but as far as I can tell, if
ivch_init succeeds, there's nothing unknown about the connection.

I've put up some RPMs for people with i830 laptops who might want to
test this out:
