Ok, the magic workaround is to disable the "Legacy option ROM" feature
in the BIOS, which happens to be the BIOS default. Go figure why the
kernel stopped liking whatever that setting implies.

I have had to revert completely to 4.2.0-35.

Sure there is something more proactive that can be done than mere testing of
new kernels and BIOSes?
It should be possible to isolate the cause of the problem by comparing the
diffs between 4.2.0-040200 and 4.2.0-35-generic, as I mentioned above.

Without the external display the system definitely doesn't come up

Confirmed that the regression is in 3.11.0-12-generic. Reverted the
kernel of the host to 13.04's vmlinuz-3.8.0-31-generic , with no other
changes to the OS, and the problem is fixed.
