It probably happens even under no-load situations.  Seems to be an issue 
between newer Motherboards / BIOSs and 2.6.16 / 2.6.17 kernels.
I see this message on my nForce 590 system (Asus M2N32-SLI Deluxe 
motherboard) as well.  Usually an "IRQ7 nobody cared" message under 
Gentoo 2.6.17.  Rumored to be fixed by a newer developer-only BIOS for 
this particular board, or possibly fixed in 2.6.18.  But since it 
doesn't seem to affect anything, it's merely a minor annoyance.  Xen 
3.0.2 also had a terrible time running on this particular system, so 
it's still running a Gentoo 2.6.17 kernel.
It's probably not Xen-specific for your motherboard and installing 
another Linux kernel will show the same message.  (Until you either 
upgrade to a newer Linux kernel or you upgrade to a BIOS that plays 
nicer with Linux.)  I am a bit surprised that you don't see it with your 
distro's stock kernel.
