I was referring to the server side.
One can certanly build a 10GbE box based on IPX2800 (or some other parts),
but at 17-25W it is not usable in NICs since the entire PCI card budget is
less than that - nothing left for 10GbE PHY, memory, etc.

I have a graphics card which requires two four pin molex power connectors, going back in time there have allway been certain perphiral cards which required external (non-bus supplied power sources for whatever reason) (hard-drive on a card, sparc on a card, pc on a card, early 90's hardware mpeg encoder, data collection device, remote mangement card, graphics card in modern mac etc), it's obviously not a general solution, but it's been done frequently enough that it shouldn't just be discarded out of hand.

Ah, ok, that makes sense.  As someone else also noted, the IXP2800
only has a 64/66 PCI interface anyway, so it wouldn't really be
suitable for the task you were referring to.
