Ok, easily done. I guess I was just cautious of adding a bunch of platform
specific code into an otherwise generic driver as there seems to be a number
of other platforms with their own quirks and it would be easy to end up with a
driver full of platform specific quirks.
That said it is probably better than the current situation in which each
platform has its own copy/variation of the generic code in ehci-platform.
Unless anyone is against this I will merge the 440EPX specific quirks into the
ehci-platform driver and submit it as part of the next version of the Akebono
patch series.

It sure was, thanks.
