another kauai ata kernel to test...

[Peter Larkowski]

Peter:

Thanks for the new kernel and all your work.  I think we (you) are 
making progress :)

This kernel gets to the mountroot prompt every time (5 out of 5), so 
that's good.  Also, I can actually run init (for reference, as there 
are a few people soft of keeping up with all this, 12" 1Ghz Alum. 
pbook, netbooted) and get to /bin/sh.  Thanks for the debugging work 
done on this Suleiman!

As for the Kauai controller, here's boot -v...  Any idea why the CPU 
speed is 768Mhz?  I know the cpu can be slowed down, and I'm guessing 
freebsd doesn't have any support for switching.  Is it actually being 
run in the slower mode, or is this a probe issue, and it's actually 
running at 1Ghz?  Just curious.
