If it's like the alc setup on an Acer Aspire One D250, the 10/100 alc 
chip is used with a 10/100/1000 Atheros PHY.  Don't remember the exact 
symptoms, but it only worked right after manually setting the media to 
100baseTX.  That was on a gigabit network, but might also help with no 
cable connected.

Rebuilding the kernel without the alc device ought to also work, but is 
less elegant.
