Yeah, it's not really on to limit HVM #vcpus for all time, to deal with one
legacy OS. We'll have to build a legacy DSDT to deploy when
hvm_info->nr_vcpus<=15.

I guess I can look into that, and also I'm going to stop checking in the
pre-built dsdt.c file. It's now really big and constantly changing, and
people who build the Xen tree are just going to have to sort out to have
iasl installed. In fact the Makefile already grabs it automatically...
