Thank you very much for helping this green hand get up to speed on the MIPS
platform.  I have successfully configured card services to work with the
current linux_2_4 CVS, in conjunction with a TI PCI1510 PCI->CardBus bridge.

There are a few card services options that you will need, in order to replicate
my work:

1. The pcmcia_core cis_speed needs to be set to a fairly low value.
   I have successfully used `modprobe pcmcia_core cis_speed=10` and 
   `modprobe pcmcia_core cis_speed=1.`

2. The PCMCIA memory window must map into the memory window assigned
   by the PCI device autoconfiguration. Since my `lspci -v` shows:

   00:0d.0 CardBus bridge: Texas Instruments: Unknown device ac56
       Subsystem: Unknown device 5678:1234
       Flags: bus master, medium devsel, latency 168, IRQ 1
       Memory at 40000000 (32-bit, non-prefetchable) [size=4K]
       Bus: primary=00, secondary=05, subordinate=00, sec-latency=176
       Memory window 0: 40001000-40002000 (prefetchable)
       Memory window 1: 40400000-407ff000
       I/O window 0: 00004000-000040ff
       I/O window 1: 00004400-000044ff
       16-bit legacy interface ports at 0001
   I configured /etc/pcmcia/config.opts as follows:

       # Local PCMCIA Configuration File
       # System resources available for PCMCIA devices
       # remember to modprobe pcmcia_core cis_speed=10
       include port 0x100-0x4ff, port 0xc00-0xcff
       include memory 0x40000000-0x40ffffff

Special thanks to Pete for answering so many of my questions.

I hope you find this information useful!
