I have a console - and have booted with
"pci=nomsi" and the behavior is ~the same or even a little worse in some case (but not by much)...
I will send kernel log & the .config file separately to you... (quite long)...
Further, you should note that my arch/ppc does NOT have MSI Capability (CONFIG_PCI_MSI) - thus I think this might be
Is there any debugging I can turn on in the proc or sysfs? that might give more clues (e.g.: /proc/sys/dev/scsi/logging_level)?

Okay, a couple of things:
Do this from a text console, not a GUI. And preferably without ever starting klogd/syslogd during init.
That way you've a much better chance of seeing some kernel diagnostic messages when it locks up.
Can you boot with "nomsi" kernel parameter? And I guess we'll need to see the entire kernel .config as well.
This is a tricky one. The driver behaves fine for me here with a 7042 rev.2 on PCIe in my x86-32 box.
