I powered it off with battery unplugged for about an hour, and rebooted
into the known-working kernel, making sure that any fancy power mgmt
features were disabled (like aspm), but it still failed in the same way.

I'm wondering if it's simply something like the socket has failed, and
one or more of the terminals isn't connecting to the card? Though that
would only show problems on card insertion, but I gather the driver is
having problems from the moment it detects the controller?
