I throw my experience in the mix: Dell DRAC cards are terrible at Auto-Neg FYI. That the only time I have had an issue recently.
Way back in the day, I worked in IT for a major University, and the old Macs COULDN'T auto at all. The major pain was not the fact that it negotiated the wrong speed, but it wouldn't negotiate ANYTHING, which would break the link altogether. Cisco switches.

Anything made in the past 5 years works great with autonegotiate. You just need to make sure neither side is hard set - that's the only time I see issues. On older equipment, I've found it works best if they are both hard set to the same thing. But nowadays, we just set everything to auto and it works flawlessly.
