I did this.  Or, rather, I pulled down the 2.0.5 kernel source and
compiled it on my 2.0R system.

It boots.  It runs.  However, networking failed dismally.  Route
and routed changed significantly enough between releases that the
2.0R routing utilities cannot communicate with the 2.0.5 kernel.
I believe I also tried to compile the 2.0.5 route, but was still
unsuccessful in that.

There may be other incompatibilities; I haven't come across many
yet (though my system is, admittedly, pretty bare-bones).  I plan
to just do a full upgrade to 2.1 eventually.
