Mmm. I guess that's missing _hurd_init initialization. It would
be tricky to separate out the really basic pieces from proc/auth
initialization, I'd say it will be a lot less tricky to just make
hurd_pci.c use the dir_readdir RPC directly on the root port instead of
going through the readdir layer. dir_readdir is not that complex to use.
Similarly, if pci_device_hurd_read_rom ever gets to be called, use
dir_lookup/io_read instead of open/read.
