    The second.

Ok, at the risk of appearing totally dumb, I'll double check.. If the second ic correct, PCI1510 is a bridce, a cardbus card cannot work.
 

    You can see yourself that PCI1510 is a bridge (Cardbus-to-PCI bridge is
largely the same as PCI-to-PCI bridge).

Ok.

    Think again. :-)

Ok, that's a typo :-) It should NOT work. Is this better?

   Sounds like what's been told in the errata 32.

It seems that  Au1500 slowly faded into the shadows. Now it is owned by Raza, but there is no sign of an errata document, perhaps I've lost the magic moment when a lot of documentation was available.

But still, the question remains: how can Takeyoshi's "Ricoh CardBus Bridge" work with a cardbus card if bridges cannot work with Au1500's PCI?

Scrub scrub..
