Controller Order

[Mark Anthony Lisher]

In the Linux 2.1.131ac11 aic7xxx driver detect my two controls correctly,
Linux 2.2.0-pre6-ac1 is detecting them in the reverse order and not
reading the SEEPROM on the 7880.

I have tried the aic7xxx=reverse_scan on the kernel command line but it
makes no difference.

This swap has occurred before in the 2.1.x before 2.1.131 but was fixed.

Below are the are the configuration of the controllers in
linux-2.2.0-pre5-ac1

Please email me if you require more details about the system or if you
want me to try anything.

Thanks

  Mark
