Multiple host adapter question

The aic7xxx for Linux finds host adapters in a sequence from lower 
chipset # to higher ones.

This causes NO possibility to have a boot disk with a host adpter
having a newer chipset.

In my example i use a 2940UW and a 2940W in PCI 0 and 1.

To work arround my problem i found two short aic7xxx.c ways to fix it.

1. Scanning for adapters from new to old versus old to new in the
   loop starting with " for (i = 0; i < NUMBER(aic7xxx_pci_devices); i++)".

2. Exchanging rows of the aic7xxx_pci_devices table to get my favorate first.


IMHO the "better" way should be to use the PCI slot #
in a lower # comes first scheme.

Ideas welcome.
