Here are excerpts from old bootstrap logs -- I don't have any of these boards handy at the moment, but I'll have access to a couple in a few weeks' time:
defxx: v1.10 2006/12/14 Lawrence V. Stefani and others tc0: DEFTA at addr = 0x10100000, IRQ = 2, Hardware addr = 08-00-2B-A3-66-C8 tc0: registered as fddi0 tc1: DEFTA at addr = 0x14100000, IRQ = 3, Hardware addr = 08-00-2B-A3-A3-29 tc1: registered as fddi1
defxx: v1.10 2006/12/14 Lawrence V. Stefani and others 0000:00:06.0: DEFPA at addr = 0x41071000, IRQ = 57, Hardware addr = 00-60-B0-58-40-75 0000:00:06.0: registered as fddi0 0000:02:00.0: DEFPA at addr = 0x41510000, IRQ = 57, Hardware addr = 00-60-B0-58-41-E7 0000:02:00.0: registered as fddi1
Compare the addresses reported with the OUIs of the respective manufacturers -- the former is DEC and the latter is HP. See http://standards.ieee.org/regauth/oui/oui.txt for a reference.
