Using the 64bit compiler, compile XFree86 for 64bit, and again 
for 32bit with gcc -m32.  Then compile XFree86 again under the 
32bit OS separately using gcc 32bit.  I recommend disabling font 
and documentation generation to get more accurate results.

For those that don't go through with it, the results of a 32bit
compile vs a 64bit compile are pretty great.  ;o)  I don't know
the results for a 32bit compile using 64bit gcc under 64bit OS
are though.  Nor what using 32bit compile with 32bit gcc under 
64bit OS are.
