the DMR does not support wake-up as far as I know. I have not found 
the time to investigate possibilities support wakeup in the drivers 
for the Express and iTunes edition of the Keyspan Remote packages 
either.

The only Keyspan remote that does support wakeup in conjunction with 
Remote Buddy right now is the Keyspan RF Remote for Front Row - but 
it's RF based, so the Apple Remote can't be used with it. It brings 
its own remote, though - which isn't a beauty, but it works nicely 
and offers a couple more buttons.

Hope that helps!

Thanks for the praise! :-)

Best regards, 
Felix
