Did you measure the nps of the chess programs? Crafty for instance exists for
Windows as well as for Linux.

I use VMWare (www.vmware.com); it slows down i.e. the Shredder engine less then
10%, what means if you run Shredder in a virtual windows machine under Linux,
your 3 GHz computer is as fast as one with 2,7 GHz. But VMWare costs money. A
free emulator is qemu (http://fabrice.bellard.free.fr/qemu/), but I've never
tried. Maybe somebody here can measure how fast a chessprogram runs under
Windows in qemu.
