We sent a patch for this to Jeff recently that allows setting of 'arbitrary'
speeds. Unfortunately the interface is rather crude but it works (for e1000,
and possibly all other nics) to set any combination of advertised speeds.
e.g. `ethtool -s eth0 advertise 0x0f` advertises all non-gigabit speeds
I haven't seen the patch merged yet upstream though.

Garzik has ACK and pulled in the ethtool patch which allows you to set
multiple auto-negotiation advertised speeds.
