As Andrew C Aitchison already pointed out, you have to start X
with a "-cc 4" option for 24-bit visual to be default. If you are using
xdm, simply change the appropriate line in /etc/X11/xdm/Xservers to
:0 local /usr/X11R6/bin/X -cc 4
There was another problem with overlay: Matrox driver goofed and
filled 24-bit areas with some values instead of colorkey, so that e.g.
XMMS window looked completely black. This bug was fixed in CVS in
October, so it is probably still present in RedHat 7.2.
