TI1520 Cardbus with CF troubles

Greetings:

I'm working on getting some cardbus support into a 8540 based platform.

We're using a TI1520 cardbus controller (pci<->cardbus bridge) and compact flash.

(Note: this is using 2.4.30 kernel.org kernel + some patches from the vendor)

At first I was getting no interrupts when the yenta driver was starting up, but I back ported some stuff from 2.6 and now the ti1520 is routing the interrupts properly through pci:

[root@mbc80-4 01]$ cat /proc/interrupts
CPU0

 8:          0   None      Edge      rtc
83:      12106   OpenPIC   Edge      enet_tx

102:          0   OpenPIC   Level     sbqe0
104:          0   OpenPIC   Level     phy_interrupt
BAD:          0

I have a cf card in the second controller socket. I've strewn printk's all over and what I'm finding is that pcmcia_request_io is called with base=0 numports=0x10, ioAddrLines=4, and returns with a base of 0x8100.

Here's the pci dump of both functions of the TI device (note, the card is plugged into the socket associated with func 1 not func 0):

I added printks to the ide do_probe, and all hwif->INB() calls return 0.

My /etc/pcmcia/config.opts adds the following lines:
include port 0x0000-0xffff
include memory 0xe0000000-0xeaffffff

Any ideas?
