That might be difficult.  How many such systems are still alive, and
are still capable of running X?  :-)

Keep in mind that I was talking about 11-12 years ago, when nobody (I
knew) had >100MHz systems.

Why did (does?) font rendering block all other operations in the X
server anyway?  That was the real source of the problem.  (For all I
know, this could have been fixed a decade ago though.  I had a FPU in
all my systems, so I never cared that much.  ;-)
