No, I tried Ubuntu Linux 7.10 Dapper Drake and it also did not find any PCI devices.
While I will be keeping my motherboard, I will be still selling my 3700+ San Diego:
I used it from 01/11/2006 until approximately May, 2007. It was ran at 2211 MHz its entire career because of a fault of Gigabyte motherboard: 200 MHz BIOS = 201 MHz Operating system. I still have the original packaging, bundled heat sink, and instruction manual / certificate of authenticity. It was never lapped, and only seated once. Private message me if you are interested.
*Waits for Joe's message.*
DUDE! I cannot believe this! When I bought the processor 26 months ago as a cheap processor, it was $307. To get a modern, Socket AM2, 2.2 GHz processor is $37. That same $307 can buy you an AM2+ Phenom 2.3 GHz black box and a darn good air cooler.
