How common is that in your experience?

Yeah, in some cases..

Well there's still the binary blob problem.

If the EC has it's own firmware then coreboot just needs to know how
to cooperate with it, but for ones where EC firmware is stored in the
BIOS flash - there's a bit of a problem with coreboot..

Granted, those ECs don't seem to be so popular. (yet?)

Sorry - I don't remember which board or SMSC controller it was.
Hopefully Uwe will see this thread and fill in.
