I finally got 10.5.2 working on my AMD64 3200+, DFI Lanparty nf4 Ultra-d. However, this morning both nforce4 lan and marvell yukon stopped working. I keep getting a self-assigned ip (169...) no matter what I do. They both work fine in windows. Help me!!

I forgot to mention, I'm connected directly to the cablemodem, no router.
