We usually have coreboot related vendor names for ACPI tables (eg.
dsdt table id 'COREBOOT'). Those are visible early on in dmesg, I
think.
Also our cbmem utility (coreboot source tree, util/cbmem) can print a
coreboot specific table's content.

Neither of these are guaranteed to be around (it would be possible to
cloak things thoroughly), but it's likely that they are on coreboot,
and pretty much non-existent otherwise.
