igb shouldn't be included by default in the common-pc-64 base, so
remove it.

Looks good. Do you agree that this would be part
of any 1.1 point release as well, or is this purely a
1.2/cleanup activity ? If it's the latter, I need to wait
for the 1.1 sustaining kernel to be created.

I think this is all purely 1.2/cleanup. It does fix a bug, but not a
serious enough to make it into a point release, IMHO.
