that is probably correct but .. just for sake of completeness.. which 
exactly C3 cpu is this ? Pasting /proc/cpuinfo would give good 
information.
I also expect to send updated patch to the list on Monday which should 
address all know in issues. FWIW, the issues I ran so far and fixed were:
        1) lack of 4mb page tables
        2) lack of support for CMOVE

also, I have this weird problem where the /etc/init.d/xend does not seem 
to work anymore with 4kb pages (as tested on pentium 3 with PAE disabled). 
That seems quie weird. any ideas?
Adam,
who ponders if there exists 686 python version with cmove support... me 
goes off to check.
