Sure. I've created a board support package for OpenRD base which is
still basically a copy of sheevaplug. I can submit it if Prafulla wants
to, but it's very preliminary still.

The problem with the phy_reset was simple though: The phy simply has a
different address than the one for sheevaplug. The patch below (against
my board package - not possible to apply!) fixes this.
