OK.  However, notice that the XInside server (AcceleratedX) is
incredibly memory-hungry: it consumes approximately 3 times as much
RAM as a similarly configured XFree server.  It is faster, no doubt
about that, but consider this:

Start X (1280x1024, 16bpp), run olvwm, a couple of xterms, an Emacs
and Netscape, edit a few files, browse a little.

AcceleratedX will happily start at around 12M and proceed to take up
around 20-24M of RAM, while XFree, with the same treatment will stay
at approximately 8-9M.

This led me to replace a Matrox Millenium with an XFree-supported card
(in this case, a Diamond Stealth64 (S3 968)).  X is slower (about half
the speed of AcceleratedX on the Matrox, as measured by xbench), but
the system is overall much better.  It used to be the case that a
machine with 32M would constantly be swapping because of the X

After the swap, the system feels much better.  I tried the same thing
on a notebook and got similar results (AcceleratedX would be 4x faster
gain and take up 3x more memory).  Note that for the portable, the
XFree server used was XF86_SVGA while in the desktop system it's
obviously XF86_S3.

My conclusion: if you want to stick with the Matrox and AcceleratedX,
you'll need at least 48 or 64M. (for 1280x1024, 16bpp).
