[PATCH] Avoid 10x7 heuristic, handled by server

[Stefan Dirsch]

From: Frederic Crozat <fcrozat at suse.com>

Remove the 10x7 heuristic, since the server has equivalent code now.
Instead, disable "acceleration" under qemu, since taking the hypercall
trap is really quite expensive and you're better off doing noaccel.
