I haven't found a way to make it beep, and no-one reported success when
I asked about it here:
http://thread.gmane.org/gmane.linux.debian.devel.eeepc/852
But this doesn't mean that removing the speaker driver would remove the
delay. It would just be some other driver that would block instead
while the slow mouse initialisation runs. The problem was that for
each bus, each driver is matched against each device in turn and it
waits for the device's lock before matching. The patch that I linked
to eliminates this locking.
Cheers, Phil.
