[PATCH] PCI fixup for old NCR 53C810 SCSI chips, kernel 2.4.18 [not wrapped]

[Graham Cobb <g+linux@cobb.uk.net>]

Repost of my patch for DECpc XL systems and other old motherboards using the NCR 53C810.  
This one should not be wrapped by my mailer.  Apologies for the earlier mail screwup.

Graham
