atkbd_timeout() period?

Hi,

As I see, one of the most active threaded callouts on idle VMware VM and
some hardware is atkbd_timeout(), called 10 times per second.  Plus it
is also one of few remaining non-MP-safe callouts.  According to the
comment it seems to be only a workaround for some lost interrupts.  That
makes me thing: is it really needed to run so often and so accurate, or
may be we could reduce it to 1-2 times per second?  Or may be it can be
avoided somehow 20 years later?
