It's back!

I'm trying to run xenoprof on an Intel VT platform (955 processor) under the 
latest xenbits unstable (well, when I downloaded it last night, it was at 
changeset 10031, and I'm getting the following when I run opcontrol:

You cannot specify any performance counter events
because OProfile is in timer mode.

The opreport command line in question is:

opcontrol \ 
--vmlinux=/home/raybry/xenbits-unstable.hg/linux- \  
--xen=/home/raybry/xenbits-unstable.hg/xen/xen-syms --active-domains=0 

The xen command line in /boot/grub/menu.lst includes the lapic option:

title XENbits unstable xen
    root (hd0,1)
    kernel /boot/xen.gz lapic dom0_mem=512M tbuf_size=100 com1=115200,8n1 
console=com1 cdb=com1 sync_console
    module /boot/vmlinuz-2.6.16-xen root=/dev/sda2 selinux=0 showopts 
psmouse.proto=bare lapic
    module /boot/initrd-2.6.16-xen

Attached is the xen.dmesg, the linux.dmesg, .config file for the 
linux- kernel, and some system info.

Any suggestions would be appreciated.
