I like this idea but I have some suggestions about the general approach.
I think instead of defining another machine type, it would be better to
just have a command line option like -cpuid that took a comma separate
string of features with "all" meaning all features that the host has.
I also think it would be nicer to use cpuid() directly instead of
attempting to parse /proc/cpuinfo.
