Comment:
The "EC port 6c output buffer timeout" message occurs because the EC port
6c command sequence takes too long to complete. The timeout in OFW is
currently set to 1 second, which ought to be enough time for the EC to
respond.
We need to either fix the EC code to handle port 6c more reliably, or
eliminate port 6c commands entirely, instead using AUX port multiplexing
to transmit commands and results via the normal PS/2 port registers.
