How does one boot a PVM into single-user mode?

I've been messing around with trying to understand how a PVM boots lately, and I have a question:

Suppose I got my server hosed enough that it won't boot. How do I boot into single-user mode, to fix the problem?

With a 'real' server, I just interrupt the grub boot process, add "single' to the end of my 'kernel line' in the grub.conf, and boot. But PVMs don't boot that way. Through some Xen magic, the kernel boots without using the installed grub inside the VM. I could mount the VMs first disk into another VM and edit the grub.conf kernel line, but that's pretty awkward.

Isn't there a better way?
