Interesting... The reporter of ticket 2195 claims his board is the
same like yours yet his SMSC chip has a different device ID. Maybe
yours is something compatible to the dme1737...

This is indeed unknown. Can you check the markings on the chip so that
we know what we're dealing with? From the product picture my guess is
it's the chip in the QFP package close to the IDE connector. It should
read something like SMSC xyz.
