If you are getting a motherboard with an onboard NIC, just make a note of
the chipset. I bought an Asus P5K-VM board with Marvell 88E8056 NIC chipset
and there is no way this one can be made to work under Linux and I really
tried hard. There are reports on the web that some revisions do work better
than others, however mine was one of the bad ones. The same bad chipset
apparently is also used on some Gigabyte boards...
