I agree with you. The platform does not provide many identification
points. We have specific hardware such as the CPU, Ethernet, Cardbus
and USB controllers; there is no DMI available; no PCI bridge subvendor
info, only the BIOS provides a 16-bit identification call...
We discussed that point in https://lkml.org/lkml/2011/5/4/437 without
success.

What would be the proper way in your opinion?
