Good point. Try running:

./msrtool 0x200000{18,19,1a,1b,1c,1d} 0x4c0000{0f,14}

in Linux started by factory BIOS. Note that you need /dev/cpu/*/msr
available to run msrtool in Linux. Unfortunately, msrtool is not
currently available as payload, but perhaps coreinfo can be used to
display MSRs?

(It would be nice to have msrtool diff mode available in coreinfo,
using a file stored in cbfs for comparison!)
