we only support f2 or later. This should die.

don't know how to autodetect this ... it is a wiring on the mainboard thing.

Is this in v3? I thought I had killed all these.

Ditto. That should be dead.

This is detectable and stefan is going to tell us how.

config variable. Don't know how to do this dynamically.

yes, these are trivial to detect at runtime.

This ought to be determined somehow but not sure how.

These are hard, but we can try.

agree. But let's do the easy ones first. Starting with
FREQ_1G_support: all F2 are ok with 1G, right? We don't need that
