Update:  I still don't have a clue why the 2.0.2 X server runs
with a 2.0.2 kernel but crashes with a -current kernel.

The big X11 lump-o-code downloaded and compiled.  But attempting to
run the X server got some dynamic linker error.

Added export LDSTATIC=-static, removed the X server binary
and kicked off another build.

So now I get a static linking error.
