Subject: minimal X server (XF86_SVGA)?

Hello,

Yesterday I updated XFree86 to 3.3.2.  Only included drivers are
mga and generic for XF86_SVGA (Matrox Millennium).  ps shows

USER       PID %CPU %MEM   VSZ  RSS  TT  STAT STARTED       TIME COMMAND
root     20468  1.9 20.5  4188 12988  ??  S     3:02AM    0:08.74 /usr/X11R6/bin

X is running at 16 bit for 1240x1024 and it doesn't have PEX, XIE, etc.

Here are my questions:
1. What is the minimal XF86_SVGA configuration/memory footprint
running at 1240x1024x16?  Video card has 4 MB.

2. What are the extentions and drivers that can be left out to achive
minimum footprint?  (E.g. I doubt if I need generic driver at all,
and I don't think I need PEX, XIE et al for "normal" applications.)
I have attatched xdpyinfo output below.

Thanks,

	J Han	hjh@best.com
