Exactly, we started to discuss on it on the irc channel.
I didn't spent time on it since a while, sorry for that.

I think the scripting language should also be capable of parsing the 
other "hardware" stuff like the dmi table etc..
This could be very usefull to make some rules depending on the hardware 
configuration.

Curtis, IIRC vmx & svm flags are not detected in the current 
implementation of the cpuid com32 module.
If someone have the hardware to make a patch ;)
