Problems: - Detection of the primary adapter is broken. You have to set explicit PCI id in XF86Config to get the card detected as *secondary*. However, switching to VGA text console won't work then (most drivers don't save/restore VGA state for secondary adapters). - Rather old bug in mga driver (since 4.1.0, IIRC) - the driver attempts to read the video ROM *before* enabling it. Naturally, this causes annoying machine check on certain platforms. Full details of bug and original patch submission are in Red Hat bugzilla: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=91711 I've updated the patch to cleanly apply to X.Org CVS, attached below.
