Sorry. I got the message completely wrong. I really was:
| PCI: Enabling device 0000:00:0c.0 (0000 -> 0003)
| sym.0.12.0: MMIO base address disabled.

| 0000:00:0c.0 SCSI storage controller: LSI Logic / Symbios Logic 53c810 (rev 02)

| I/O ports at 1000 [size=256]

So I used them for a test kernel, built from kernel-source-2.6.8 and
your little debugging patch applied. What happened is this:
| map 0xc4000000 length 128 returned 0xf4000000
and the kernel initialized the SCSI controller correctly - as I could
verify, this is due to the backported patch from 2.6.9-rc2 that Hollis
Blanchard sent here earlier in Bug#271852. So that problem will be
solved in the next revision.
Thanks for your time and help.
Regards, Jens.
