Re: Silence on boot with Dreamplug. [fixed]

[Ted Lemon <mellon%fugue.com@localhost>]

It turns out that the problem with the dreamplug was really trivial: it reports 
a different value when the kirkwood clock code tries to figure out the CPU 
frequency.   The following patch results in the kernel booting all the way up 
to the root prompt:

                }

Here's the boot output:
