Alas it runs very well, but doesn't include what I was hoping for.  I've
been using 12.1.0 os2 as a base for the demo XO1 machines because that
build has a kernel that has the fix for the SISUSB load errors.

However, in the bug track, DSD does also provide a pointer to a test kernel
using F14 that does incorporate the fix.  So, now that I know how to update
a kernel, I can use a production 883 as a base, and then can accomplish
what I need by updating using that test kernel for the demo machines that
need this USB2VGA2 function.

Going forward, I think the fix will be in the new kernels.

I'll play some more and see how much I gain.  By the time I'm done loading
up the XO1, there can be less then 200Mb available to those users who don't
want an SD card solution, so this might still be good, relatively ... :-)
I'll be trying Mikus suggestion tomorrow.
