I wasn't implying that video did affect ethernet. I did not check for
DMA error messages. What I know is that I couldn't log in remotely,
which _happened_ to coincide with being headless. I think it unlikely
that being headless is the problem, as that's how the machine has run
for most of the past year under 2.1, and I hadn't heard of anyone else
with that problem in 3.x either. But I could be wrong...

Again, as my assumption was simply an intermittent booting problem,
"worked fine" meant that it did in fact boot. Beyond that I hadn't had
time to diagnose.

This is true. The problem is finding the time, and then seeing if I
remember how to do a serial console, and then hoping I can find the
cable to do it with. :)
