The status codes look bogus. In 0.10.5.10 there is a code path through
reset where status is not set if the chip is not brought out of low
power mode. Why this might happen is beyond me (could be a cardbus
problem) but if you initialize status to a known value before the hal
calls that are failing this might confirm that as the problem. I've
fixed the hal fwiw.
