#1299: q2c01 firmware doesn't boot Linux by default

Comment (by wmb at firmworks.com):
The previous analysis was almost correct. The actual location of the
spurious characters was the serial input buffer, not the keyboard buffer.
The problem was that the UART RX line was not being pulled up, so systems
without a serial dongle were susceptible to crosstalk from the UART TX to
the UART RX line.
The correct fix is to turn the UART RX pullup back on. svn 287
The fix will appear in Q2C04 or the first official release thereafter.
