7388 - snapshot initializing interrupt table

I'm now back at the state of commit 7382 (including 7376). The existing
print to screen surprisingly seems to work without reset-looping, but when
I step through I notice that the lidt isn't doing what I expect.

Desired: at address 0x7cce, the processor executes:
  0f 01 1e 00 7f  # lidt ds:*idt_descriptor

Observed: at address 0x7cce, the processor executes:
  0f 01 1e        # lidt ds:*esi
As a result the next instruction is:
  00 7f fb

So the `fb` isn't interpreted to enable interrupts. So the problem of commit
7376 is latent.

Past this point the instruction stream is lined up again, and everything
occurs as it should. Purely by chance.

I fully expect all hell to break loose again, like it did in commit 7376,
once I debug the lidt encoding. There's still something I don't understand
about enabling interrupts. Perhaps I need to fill in more entries in the
table.
