Demystifying the network woes

I've noticed that my network is (mis)behaving in pretty much the same way as it did in Ubuntu 9.10.  I've begun digging up some resources to see why it's happening and it looks like a BIOS/firmware issue where the interrupts are not being set correctly by the BIOS.  You can read more about it here and here and here.  The problems described are EXACTLY THE SAME as the ones I'm having.  The question is, which one do I grab for the motherboard DP55WB?
