 Actually, the standard configuration is that /dev/mem is read.  The
code to read from /dev/(u)random isn't activated in any situation in
the standard upstream X distribution, and given that it contains an
error that stops it from compiling[1] I suspect that it has only ever
rarely been used.

 Obviously the correct thing to do is to shift to using /dev/(u)random 
by default.
