XVR-600 in a Sunblade 1000

Hi Folks

Just ordered an XVR-600 frame buffer from ebay.fr. Seems quite rare to
find them on this side of the pond and the price was ok.

I got it for a couple of reasons. Last year I found a really nice Philips
220EW monitor in the supermarket but it doesn't work with the standard VGA
of the Sunblade, moving to DVI should make it work.

I also installed this yesterday and have been having a lot of fun pitting
bot armies against one another and joining in from my G5.

Works fine under Solaris in server mode but graphics performance is pretty
dire when trying to play even though CPU usage only ever goes up to about
40%.

One question, what do I need to do to Solaris 10 after the card is
physically installed? I seem to remember running boot -n to rebuild /dev
when adding a tape drive but I've never added a new frame buffer before.
Do I need to do the same here? What about OpenGL drivers etc? Are they all
there in a standard Solaris 10 install?

Best regards

Ben
