Back in the old days I had a trusty desktop 286 which sat on a piece of
furniture at approximately knee level, with a very prominent "reset"
button on the front panel... need I say more?

First make sure all your filesystems are ok (touch /forcefsck and reboot).
Second, I am not sure whether eix is complaining about the portage tree
metadata (which is rsynced with the rest of the tree and not kept by
emerge, so it shouldn't get corrupted) or its own cache.
You can regenerate the former locally with emerge --metadata; if it
doesn't help (and I don't think it will) I would try deleting the
contents of /var/cache/eix and manually running eix-update.

HTH,
