Andrew,

I confirm oprofile (0.96 on my fedora 14) works just fine (see below).

Do you recommend me to use the latest (git) version ? 0.96 is quite old (2011)

Could you explain me a bit how to get sample counts corresponding to the complete benchmark (few minutes long) ? should I use the event argument to set the highest count (reset) value ?

By default, oprofile uses: CPU_CLK_UNHALTED:100000:0:1:1

opcontrol --event=CPU_CLK_UNHALTED:400000

What is the maximum value I can set ?

IME it Just Works. The oprofile shipped with Linux distros has everything you need, and you just need to use -agentpath: when you start the VM.
