Nothing wrong with the patch (although I'm reminded of the /usr/lib42  
thread ;-)

But it would be nice to be able to support the probe dependency
	Requires: cpuinfo(foo) = bar
on systems without /proc.

ATM, "support" on non-linux menas generate a cpuinfo-like text file,
and point the probe dependency parser at that file. A better  
implementation
would use the values provided by the native kernel. Note that "foo"  
and "bar"
in the probe dependency are already quite opaque and arbitrary.
