serial console install - boot-floppies woody 3.0

["John H. Robinson, IV" <jhriv@ucsd.edu>]

doing a serial console install on i386 architecture, serial console, i
noticed upon reboot that everything went smoothly until base-config
completed, and the getty was spawned.

T0:23:respawn:/sbin/getty -L ttyS0 9600 vt102

my console was using 115200 bps, not 9600.

the ``console=ttyS0,115200n8'' was passed to the kernel at boot time, so
the serial speed was in /proc/cmdline at install and reboot time.

it looks like update_console_info() in
./utilities/dbootstrap/baseconfig.c is the place to fix this.
