[uCsimm] ucsimm-head.S broken?

    I have started the attempt to bring uClinux up on my platform and
have a question about line #43 of the
../linux/arch/m68knommu/platforms/68EZ328/ucsimm-head.S file. The
instruction there is a 'movew #0x10B, FFFFF902' and the comment is that
it is setting the baud rate to 9600, but this value doesn't set it to
that rate. I haven't taken the time to calc the baudrate, is the comment
incorrect? It could be that this value does set to 9600 and as I am
using a 12pf Xtal on the PCB (not the recommended 6pf), I could be
running fast on the Xtal. A value of '0x0038' (as advertised in the
manual) does give 9600 baud.
