2.6.x kernels & PCI-to-PCMCIA bridges [again]

Please remove SS_CAP_PAGE_REGS from the pd6729.c
and try again.

-	sockets[i]->socket.features |= SS_CAP_PAGE_REGS | SS_CAP_PCCARD;
+        sockets[i]->socket.features |= SS_CAP_PCCARD;

It seems the pd6729 driver does not work
if memory probe is 0xa0000000-0xa0ffffff
in your PC.

Best Regards
Komuro
