That's ok for now. I will test on one of my systems and add the needed PCI 
ID(s).

There are many, I'm sure. For example some PPC4xx variants which could use 
this EHCI support. So I'm pretty sure that patches for supporting other EHCI 
controllers will follow soon once your patches hit mainline (next merge 
window I suspect).

Thanks.
