Just tried it on pcm030. If I uncomment the reg line the kernel won't
boot at all. I don't get any output.

I hooked up a serial console instead of netcat.

Yeah, there current PCI driver in mainline expects the bootloader to
set stuff up for PCI to work.  I've fixed some of it, and the fix is
queued up in Ben's -next tree.  Can you try Ben's -next tree?

Thanks,
