ips 2/4: 2.4 resync 

From: David Jeffery <david_jeffery@adaptec.com>
(with minor fixes for rejects)

This patch is a resync with the 6.10 driver for 2.4 and updates the 2.4
compatability code.  It adds a new wrapper function for differences
between the 2.4 and 2.6 scsi proc interface,  forces pci posting in 3
places, corrects using a meaningless constant of 0x80 to 0, and syncs
comments that had changed.
