These look good.  IIRC, the kernel I tested with also had:

device		sio2	at isa? port IO_COM3 irq 5 disabled
	or
device		sio2

in it, but I may be misremembering.  Just make sure that you use the
config entry that gives you a port at 0x3e8, since most laptops have
COM1 and COM2 which really cannot be disabled (well, the BIOS says you
can disable them, but I've seen a few where the BIOS disabling is
broken).

: #options                EXTRA_SIO=1

This is totally bogus and should never ever be used.  Better to remove
it completely from your config file, lest the temptation is there to
use it.

: options         HZ=500

I don't think this option will work, but I don't think that's what is
breaking things.
