Re: port-cobalt/44292: -current kernels do not work on (my) cobalt qube 2 since one (1!) year

[Izumi Tsutsui <tsutsui%ceres.dti.ne.jp@localhost>]

Reverting part of src/sys/dev/ic/com.c rev 1.298 seems to fix the problem.
(201007200000Z works, 201007210000Z doesn't)

Needs to use device properties to enable prescaler?
More initialization is required?
