We installed to a second CG5 board into our SUN 4/260-CXP running
OS-4.0.3.  After installing a modified cgtwo-driver, we are now able to
use two desktops at our system (/dev/cgtwo0, /dev/cgtwo1). 

In contrast to the SUN documentation on the GP2, we were only able to run
the first CG5-Board by the GP2 (/dev/gpone0a), while gpconfig refuses to
bind the second CG5 to the GP2. (e.g. "gpconfig gponeo cgtwo0 cgtwo1"
fails)

The GP2 documentatation says, a GP2 can drive up to three CG5-boards.
Nevertheless, SUN Germany claims, this is an unsupported configuration,
and does not provide any assistance.

Does anybody run multiple CG5's in a SUN 3/260, 4/260 ? Is there a patch
available to make both boards work ? Any hints will be helpful.
