Not really - I suspect there's something else going on.

When yenta initialises, we claim the PCI resources for it, and disable
the legacy IO space by writing 0 to it (it reads back 1.) This is the
same that we've always done.

I wonder if the PNP code is activating the legacy IO space, and thereby
screwing up the configuration which yenta has setup.

Could someone with both yenta and i82365 with PNP try running lspci -vv
after both have tried to initialise, and obviously before inserting a
card in a slot? You should see:

16-bit legacy interface ports at 0001

as the last line for each of the Cardbus bridge devices.
