I am planning to send hex to MSR_hex in next series along with :-
1. IO_hex : (IO registers)
2. PCI_hex : (PCI defined configuration space)
3. APIC_hex : (APIC memory based registers)
4. CPUID_hex : (CPUID Instruction registers)
5. MSR_hex : MSRs
Which will give almost full information of CPU state and will be more
useful to users and developers.

Yes. I will also support it as I said above.
