   When I read this I just had to try it myself.  If only it worked....   
      
   With all my USBUHCD drivers rem'd-out and just USBEHCD active, my   
   USB keyboard and mouse were dead.  However, USBEHCD did disable   
   legacy mode when I had it enabled - and it still took 70+ seconds.   
   It's further proof that USBEHCD causes the delay that I experience.   
      
   A question, Lars...  Does the EHCI controller actually participate   
   in the support of legacy mode or just in disabling it?
