Doug's looking at me when he says that. :-)
We talked about this last night at BAFUG; right now, even if smbios(4) is able
to find the SMBIOS info -- it currently only looks at the aforementioned
0xf0000 - 0xfffff range, so it can't find it on UEFI -- smbios(4) doesn't
actually provide any interface for that information. Doug and I have talked
about making smbios(4) useful, by parsing the data and providing KPIs and APIs,
for years now; I think I'll *finally* have the time and motivation to do so
