PCI/SCSI help

[acurtis at directvinternet.com]

I am in the process of implementing PowerSpan PCI support into the 8260 PPC
tree. It appears that all the translations are working but when I try to use
the SYM53C8XX SCSI driver, it fails during the script execution for the
snoop test. I have tried both versions of the SCSI driver with the same
results. The ncr_snoop() test terminates with a script execution error.

Below is a log of the boot messages with debug statements. If anything looks
out of the ordinary please let me know.
