You want macmodel mini-internal or mini-external (mini is an alias for
mini-external).  The macmodel option only affects the output
enumeration, so selecting the wrong one will enable the wrong outputs
(VGA/DVI/LVDS/etc.).  Also, the ati and radeon drivers are the same
thing.  ati is just a wrapper that loads radeon, r128, or mach64
depending on the hw.  the ibookhacks option must be some openbsd
specific patch.  If you can point me to the patch I can look at
incorporating it into the upstream radeon driver.
