Hmm, looking around the 2.4 version of this code, I wasn't entirely 
comfortable with the way the code configured these TI bridges - it seems 
to try to configure older chips in the same way as newer chips - and it 
can end up writing to reserved registers and/or invalid values to 
existing registers on older chips...

These might be of use:

http://www.buttersideup.com/files/ti1031.patch

the last is a patch against linux 2.4.20 that I used to get my TI1031 
based SCM Microsystems "PCI Swapbox" to work.  Haven't had time to 
finish it up, or forward port it to 2.5.x yet unfortunately...  It is 
based on an earlier patch by Pavel Roskin, which - I think - got applied 
to -ac

Cheers,

Tim.
