I didn't do anything, it just worked that way.

I had to return the machine, because it wasn't reliably using the second
memory bank.  They decided it was defective, so I'll get a different
mainboard in a few days.

The problems I experienced with the Mac Mini Duo with the kernel patch I
downloaded last week:

  - The video seems to start a few lines down.  I can use it if I specify a
    height a bit less than my real height (I used width:1600,height:1192).

  - No sound output.  The driver loads fine, but no mix/configuration
    settings seem to make any sound.

  - Fully unaccelerated X.  Oddly enough, the unaccelerated X server
    performs better (x11perf) than my 2.2Ghz AMD64 (32-bit mode) with an
    nVidia GeForce FX 5200.  Things like scroll500 are nearly twice as
    fast.  Must be a consequence of the CPU having better access to the
    video memory (shared with GPU).

  - I built 'mplayer'.  Amazingly, with -zoom, it can play movies in an
    unresized window.  I've never had a machine that could do this.  It
    can't keep up if the window is made larger.  Obviously, this should
    work fine once HW scaling is available.
