I can run some full-screen app in 2001/10/20 cvs.
but, in the latest cvs, wine may crash in creating the
fullscreen-primary surface... 
(I don't know why, but since wine-server protocol has been updated?????)

ddrawtst.c is a minimal test program that crashes the latest cvs.
My environment is:
  debian2.3-woody, XFree86-4.1.0-7.
  No permission to access /dev/kmem directly.
