Interesting history of problems, but it appears to work in general, at
least for me:

That is with two Intel graphics machines running natty, both running
unity (also tested unity+metacity and metacity+metacity) with one vnc'd
to another over a wireless network.

With unity on, display updates seem rather slow but it's still basically
usable.

Googling around, I found that at one point NVIDIA had to put out a fix
(http://www.nvnews.net/vbulletin/showthread.php?p=2255561).  Pitti had
mentioned a couple months ago that this is an -fglrx specific issue,
which well could me; if that can be confirmed, we could just have
Alberto add it to the AMD bug escalation list for 12.04.  What do you
think?
