There are many different models of the DV6000; the only one ever discussed on the OpenBSD misc@ mailing list was a Core 2 Duo, not an Athlon as you have.
I would save a dmesg from a working ramdisk kernel, and place it in-line in an e-mail to the misc@ mailing list along with a brief problem description.
