Wow, there's just nothing to work with in that output.  I think the
increased debuging didn't output anything because nothing is happening,
and that's consistant with the value in the Present State register when
the driver attaches, which says that no card is inserted.  (It says
that in several ways... when a card is in, half a dozen of those bits
should be non-zero.)

It makes me think the controller isn't powered up, or is in some
suspend mode or something.  But that would be at the pci bus level, not
something the driver is in control of.  I had a problem like that
initially on my FitPc2 x86 board that has sdhci on it, but the problem
went away with a bios update.
