While it is exceedingly rare (xorg developers are some of the best...)
are you talking about it working on x86/x86_64 lihux and cygwin/x86,
and not working on powerpc Mac OS X? - i.e. as opposed to possibly
  alpha/sparc/powerpc linux and x86 mac OS X?

The reason why I am asking is that intel is small-endian and
powerpc is big-endian. It is very rare, but can't say if there could
be endian-issues in the interaction. (given that most Xvfb users are
on small-endian platforms?)

It might be useful to ask at the IRC channel #freedesktop at Freenode for 
debug tips - there are some seriously hardcore X11 guru's there... I am 
sure they like to know if you can bring Xvfb down :-).
