If it really gives a signifficant speedup this issue 
should be reinvestigated. I once was told it was slow.
That it is faster on Solaris may be as SUN has enhanced it.

It was disabled in XFree86 for quite a while and nobody
complained. Anyway, for this release its too late but
we can reenable it in the future.
