Interesting.  I misunderstood.  I thought the recent domU
are slower than old domU because the recent dom0 make recent
domU slow.  I was wrong.

With 20070627 dom0 kernel w/ my locore.S patch and Xen
3.1.0, I got following numbers.

0518 domU			10.913 real
0624 domU w/ locore patch	19.776 real
0627 domU w/ locore patch	19.776 real

So, these recent domU are slow on my machine because they
just run slow not dom0 make them slow...  Interesting, but
now I completely have no idea how to find out the reason why
my PC domU is so slow.  hehe
