I tried to run Magic on a 110, but it always came up in black and white mode.
I was working on a demo system running Sun 3.2.  I traced the problem to
the way Magic determines what type of display it is running on.  On Suns,
Magic does a FBIOGTYPE ioctl on /dev/fb which returns the frame buffer
type (amoung other things).  The 110 *should* return FBTYPE_SUN4COLOR,
but instead returns FBTYPE_SUN2BW.  Apparently, the system doesn't know
about the on-board frame buffer (/dev/cgfour0).  I checked the EEPROM settings
for the frame buffer default, but to no avail.

I have not been able to try Magic on a real (non-demo) 110 running 3.2.  I had
hoped that the demo unit had a buggy version of 3.2.  Also, I was not able
to work around this bug, as I couldn't get the source code for Magic onto the
110.
