Why? This practice made sense when 10baseT gear from different
vendors wasn't compatible, but not for the last 15-20 years.
This practice still makes sense, at least with broadcom cards.
I had spurious problems 2 years ago with a Gigabit Ethernet
interface showing lots of error while using autoneg (hooked to a
3com switch or to a cisco one).
Those problems did instantly disappear after forcing the speed on
both, the card AND the switch.
I always do force the speed on servers.
I don't say it is the only way to go, but my way to handle it.

I've had problems with bge(4)s in IBM xSeries machines that required
forcing speed/duplex, else they would negotiate to 100/half.
