Thank you, Maritin.
I tried linux-2.3.99-pre3 and your patch. Now happily the scsi
controller on the pci bus 1 was detected, but sadly it didn't work.
Under the kernel 2.2.X or 2.3.99pre2 with my dirty patch, the driver
would go its initialization or something after the detection, and the
connected scsi devices were listed such like this.
sym53c8xx: at PCI bus 1, device 4, function 0
sym53c8xx: setting PCI_COMMAND_PARITY...(fix-up)

:::
Under the kernel 2.3.99pre3 with your patch, a part of your patch was
rejected and I applied manually, the devices are not listed. And it
seems retrying forever.

I don't think it is a matter of scsi driver.

Here you are.
But I don't want you to think I have a IBM S/390 on my desk.
