I just blundered across this paper on 802.11n interference:
"802.11n Under the Microscope"
<http://pages.cs.wisc.edu/~shravan/11n.pdf>

Apparently, it doesn't take much to mangle 802.11n without or without
channel bonding.
We show that the throughput of an 802.11n link can be
severely degraded (up to 85%) in presence of an 802.11g
link. Our results also indicate that increased amount of
interference due to wider channel bandwidths can lead to
throughput degradation.
In other words, just about any form of interference will trash 802.11n
thruput. Most of the N boxes I've played with will revert to the
slower 802.11g speeds at the first hint of any co-channel users
(interfering or not including adjacent channel spillover).
