hmm... 461F0010 does not seem user-friendly, "A64FX" seems better. 

Shunsuke, what about to update the firmware strings? ;-) (as Jeffrey
suggested in RH bugzilla)

The another possibility is to exclude some vendors and do not use
SMBIOS for them (e.g. 0x46 for Fujitsu), but from my point of view
SMBIOS based solution is more elegant and ready for new CPU types than
in-lscpu hard coded tables.
