Currently oprofile's event based interrupt mode doesn't work(Bug #828) in
qemux86 and qemux86-64. We can use timer interrupt mode for now.

With this workaround, oprofile can work in qemux86 and qemux86-64.
I tested in Ubuntu 10.04.

With this workaround, we can lower the priority of bug #828 and I'll continue
to look into it.
