So if people are using kerneld to load the serial module they have to rerun
setserial every time the module is loaded?

Yes, it does. There is a warning message in the Configuration help file:

[WARNING: Do not compile this driver as a module if you are using
non-standard serial ports, since the configuration information will be
lost when kerneld automatically unloads the driver. This limitation may
be lifted in the future.]

Also I heard a rummer that in the 1.3. kernels that you nolonger
needed to do setserial v_hi. Is this the case ?

Starting in 1.2, if you are using a modern enough libc, _and_ your
application has been recompiled to use 57600 or 115200 bps, this is
already the case.
