Sure, I use:

opcontrol --vmlinux=/boot/vmlinux-`uname -r` --xen=/boot/xen-unstable-syms
opcontrol --init

opcontrol --start

<benchmark>

opcontrol --stop

opreport -l


**I changed opcontrol to echo XENIMAGE and XEN_RANGE to 
~/.oprofile/daemonrc so they are picked up by oprofiled.
oprofiled cmd line looks like:

oprofiled --separate-lib=0 --separate-kernel=0 --spearate-thread=0 
--separate-thread=0 --spearate-cpu=0 
--events=GLOBAL_POWER_EVENTS:29:0:100000:1:1:1, 
--vmlinux=/boot/2.6.11-xen0-up --kernel-range=c01000000,c03ed2ae 
--xen-image=/boot/xen-unstable-syms --xen-range=c01000000,c03fc45e
