I think I pulled in updates during freeze but not sure if that older VM was
updated at all after the freeze lifted (it may have been).

pre-Beta VM (installed at Alpha)
xorg-x11-server-common-1.4.99.901-10.20080314.fc9.x86_64
xorg-x11-server-Xorg-1.4.99.901-10.20080314.fc9.x86_64
xorg-x11-drv-vmware-10.16.0-1.fc9.x86_64

post-Beta VM (installed at Beta)
xorg-x11-server-common-1.4.99.901-13.20080314.fc9.x86_64
xorg-x11-server-Xorg-1.4.99.901-13.20080314.fc9.x86_64
xorg-x11-drv-vmware-10.16.0-1.fc9.x86_64

Thanks for the clue, but is that taking effect? Trying both
"XaaOffscreenPixmaps" and "XaaNoOffscreenPixmaps" "False" I get the same
response in Xorg.0.log, a (WW) that the option is not used.  Doesn't seem to
effect anything performance wise with the warning.  The menus *might* be a tiny
bit snappier, but windows still draw slowly.  Its interesting that gnome
terminal can scroll quickly when I drag the scroll bar, but moving it is slow
(the screen slightly tears).

The xorg.conf I was using is different, in the beta VM I've been letting X auto
add devices, while pre-beta I was not.  I'll try getting those to match.
