It seems I need to update the documentation :-)

Did you try to submit the non QEMU specific patches to Linus ? I think 
it is dangerous to leave harcoded constants in somes parts of the kernel.

BTW, in the current CVS, qemu-fast is about 2.3 times faster as the 
previous version (still 9 times slower than native on a P2 500 MHz on a 
typical 'gcc -pipe' compilation task which involves a lot of task 
switches).

I am planning simple x86 host specific optimisations to get closer to 
native performance... and SMP is getting closer now with my last changes.
