Hey JD --

I haven't been keeping up with the characteristics of the new Xfree
distributions. Is it possible to have multiple visual classes on the
same screen, or do I still need to start another session in 8bit mode?
Xfree86 development seems to have nearly ground to halt over the past 2
years, and it was my understanding that version 4 didn't end up having
overlay capabilities despite advertisement to the contrary. What's the
scoop?
