OK, i've applied your patch and got strange results:
first time i run Richards prog i got 4us. All next
values were 6us. I reboot the machine and the result
was the same!
I'm afraid i don't understand what exactly the patch
does. At first glance only the sequence of lines is
changed - so what? Or there is some relatione between
"fnsave" and setting task switch bit?

P.S. I'll try to do some profile in kernel mode
