Hi.  I just now got 5.2-CURRENT running on my Blade using the code as of
yesterday.  I'm also seeing this slow keyboard behavior.

I also see that usbd refused to start, claiming:
    No USB host controllers found

This led to dmesg, from which the pertinent bit is below:

    ...

    fwohci0: <1394 Open Host Controller Interface> mem

My guess is that the console keyboard is using the OpenBoot client
interface or is being polled in some manner.  Note the Firewire
controller didn't get hooked up either.  Neither shows up under /dev.

I'm not familiar with the Sparc64/USB code to guess at what's wrong with
the interrupt hookup.  Any ideas or suggestions?  Thanks.
