Add patches/patch-ba:
Emulate the speaker port's refresh clock bit. This is supposed
to toggle between 0 and 1<<4 every 15 microseconds. XXX: We use
gettimeofday() in the real machine instead of a monotonic clock
in the virtual machine, and we are a bit sloppy about the 15
microseconds. This should be good enough for crude loops that
measure approximate delays by counting how often this line toggles.
