I grabbed your Xpmac binary this morning and tried it out on a 3400/240
running R5.  It seemed to work well for the most part.  Very noticeable
acceleration, especailly over the XF86 server I was currently using.  I
did run into a couple problems though.

- If windows are moved around too quickly, vertical bands appear.  If I
  explicitly request that part of the screen to be redrawn (e.g. by my
  closing the xterm and reopening it), the lines disappear.

- When I passed it the wrong option (I used "startx --depth 16" instead
  of the correct "startx -- -depth 16", it off course ignored the wrong
  swtich and started up in 8-bit colour).  But on exiting X, it locked
  up the machine completely.  I couldn't even switch to another virtual
  console to kill the process or reboot the machine, so I ended up with
  a hard reboot).  For a window managers - I am using an old version of
  AfterStep that I recompiled from the src.rpm for R5.  It is version
  1.0.7a (Yes - I know it's old, but it is small, I know how to set it
  up, and does all I need ;-)

Otherwise, I have not found any other problems, and the person that uses
this machine is actually pretty happy right now, as am I ;-)  Thanks for
the great work !!
