True.  At a glance I couldn't see any alternative from PLX for faster 
PCI busses.  PLX's chips are fairly inexpensive though.  As an 
alternative could you use an FPGA as the PCI-Express to USRP MkII interface?

You might be able to implement power-over-ethernet to the USRP with this 
method as well.  No need to implement 802.3af (I think that's the 
spec.).  Even though there are no spare pairs to use for a DC feed on a 
GigE CAT5 cable there are ethernet transformers which can isolate and 
insert a common mode DC current onto a pair of CAT5 wires.
