O2Micro insertion / removal undetected

[Jerry Lundy]

Greetings.

I recently started using an HP Pavilion ze42xx laptop with the O2Micro
OZ6912 PCI-CardBus bridge. The system has a single card slot.

Under 4.X-STABLE, the system appears to work: cards are
detected and powered on and can be swapped out.

Under 5.X-CURRENT with NEWCARD, card insertion and removal is not
detected. A card which is in the slot at boot is detected during the
boot sequence and powered up and appears usable.  Subsequent removal or
reinsertion are not detected.

Previous experimentation using 5.X-CURRENT with OLDCARD had similar
results, except that I could manually enable an inserted card using
pccardc. (I don't know how to manually query and poke cards under
NEWCARD.)

 From reading the list I get the impression that O2Micro devices have
been difficult to support. I'm just about googled out. Am I missing
something basic?

Any help getting card detection to work would be appreciated. I'm
running debug on acpi, cbb, and pccard. Relevant dmesg output is
included below.

Thanks,

Jerry
