Documentation is scarce on the matter, however the related coreboot code suggests that after the ACK, the keyboard also sends the result of the self test (passed/failed). It looks like this result is never consumed here, probably resulting in further confusion for later com- mands. Let's revert this for now (if it's not too late for the 4.10 release) and break things later again. IMHO, due to the fact that there are dozens of different keyboard controller and keyboard implementations and no accurate specification followed, such changes should be tested on a lot of hardware before merge.
