Yup, the joys of life as a bottom-feeder! ;-)

Probably so. I'm using the Intel driver (courtesy of Xorg), and X still 
reports warnings as it tries to use various features of newer Intel 
graphics chips with the old hardware.

That's fine. I can't imagine how OpenGL would speed up scrolling through 
Rosegarden's Score window as a composition plays, but maybe it would. 
I'll see if it makes a difference on the desktop machines. Their cards 
support OpenGL.

Sorry, but I don't consider that offensive at all. I've used video cards 
for over 20 years, and some of my favorites were the ones designed to 
run OpenGL. I used to have a little old slow Elsa GLoria Synergy 
graphics card, with OpenGL executing natively on the card, that could 
run rings around the fancy expensive cards (at the time) when it came to 
3D games. I also used to work for a company that sold the original AT&T 
Targa video boards - ISA cards that plugged into 6MHz IBM AT computers 
and could capture and manipulate 30fps TV and movie video in real time.

I don't put down gamers - realtime games involving realistic graphics 
and sophisticated game AI takes a lot of horsepower!
