In theory, yes, but not if it's a "system overview" kind of tool not 
written by someone who knows assembler or for someone who just wants to 
call a library's "enableSSE()" function, or if the program's not written 
in C...

It would be a good thing to have this facility, and done right (not like 
text-parsing /proc/cpuinfo in Linux).
