Hello all, 

	Here is my next rev of the tsc-disable patch. This one corrects a
Configure.in typo (Caught by Gabriel Paubert), and probably more
controversial, implements a soft rdtsc instruction via do_gettimeofday.

This avoids the earlier "box won't boot" problems with i686 optimized
glibc's that called rdtsc. The rdtsc instruction will now be caught, and
faked returning to the user program the same value of gettimeofday. Yes,
its pretty hackish, but it works, albeit slowly. 

Anyway, as always, comments and flames are welcome.
