    The framebuffer has been broken with kernel 2.6 for as long as kernel
    2.6 has existed. Take it up with the kernel guys, hack on the code
    yourself, or just use VGA and X and deal.

    The man page for mga doesn't say anything about forcing the hardware
    overlay to another screen. Some X servers (radeon for one) have this
    option. Some don't. You can prowl through the X source for mga
    yourself and see if there's an option they left out of the man page--
    these do exist; "RenderColormapMode" is one I remember--but there may
    not be something like that.

    Huh? Just remove whatever's in the AGP slot and put a newer card in,
    surely? OTOH, I'm not sure what video card you could find that supports
    putting the hardware overlay on a secondary head. radeon does with
    OverlayOnCRTC2, mga doesn't, nvidia doesn't (sad, eh?), nv doesn't, r128
    doesn't. If you don't *have* an AGP slot, it's probably long past time
    to upgrade. The cheap x86 motherboard I bought in January 2000 had an
    AGP slot. Oh well, HTH anyway....
