You should try upgrading BIOS. As far as I can tell, it would be version 2.4 as of 8/7/2007.
http://www.dell.com/support/drivers/us/en/19/DriverDetails/DriverFileFormats?DriverId=HY9F0&FileId=2731098639 (I was recently given an Dell Optiplex 755, also intel Core 2 Duo, and I installed OpenBSD 5.0 on it. However, I got all kinds of errors - mainly about memory conflict - and the ATi radeon 2400 wouldn't work properly. Then I realized the BIOS was sixteen versions old (A04) and upgraded it to the latest (A20) which seemed to fix just about everything..)
