    Nope.

    Bingo! Running "lsmod" in the working vs non-working config shows that a
    whole bunch of drivers are no longer being loaded after the
    dist-upgrade. Running modprobe to force the network drivers to be loaded
    restores network connectivity.

    Thanks, dircha!

    So the question now is: why did dist-upgrade from testing to unstable
    mess around with the list of modules that are loaded at boot time?
    That's sort of a rhetorical question; I don't hugely care as I now have
    a working system [at least I can manually force the necessary drivers to
    be loaded on boot]. But presumably other people will be bitten by this
    too...

    Presumably the list of modules to load on boot is just a config file
    floating around somewhere like in /etc. Or is it dynamically determined
    during booting [in which case the dynamic detection has been broken]?

    Cheers,

    Simon
