Jaakko,

I have recently received this bug-report about picprog (Debian).
<http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=387185>

Let me summerize what we have found so far.

- When asking around various people have confirmed that picprog fails on the
  64-bit amd64 platform.
- Altering the delay-routines so that picprog thinks the CPU is ten times
  faster seems to solve the problem.
- Disabling the use of the RDTSC-instruction also seems to solve the
  problem, but not for everybody.
- On my old laptop, picprog works at 600Mhz, but not at 750Mhz. By disabling
  the use of RDTSC, picprog works without a problem at 750Mhz on my laptop.
  (Note, my laptop is not an amd64 ;-) )

To me it seems that disabling the use of RDTSC is a good idea. Any comments?
Also, maybe we can try to add an extra "delay"-option to picprog so that
when picprog fails to run on some hardware, people can use this option to
make picprog run more slowy.
