I could be wrong, but isn't 'boot.config' supposed to contain only
arguments you would otherwise enter at the boot prompt? So it should be
just a single '-h'. I have a '-P' in that file, for instance, and it
works as expected.

'sio0' in the kernel config needs a 'flags 0x10' directive in order to
make COM1 a (potential) console port. Default speed is 9600 bit/s.
