Ok, let's kill this bug already :-)
We were neglecting to invoke sunsu_change_speed() when first
setting up the keyboard and mouse ports. That's why things
were not working.
This should fix it and I'll push this upsteam.
[SPARC64]: In sunsu driver, make sure to fully init chip for kbd/ms
We were forgetting to call sunsu_change_speed(). The reason
that replugging in the mouse cable "fixes things" is that
causes a BREAK interrupt which in turn caused a call to
sunsu_change_speed() which would get the chip setup properly.
