Running PCI arbiter on stock Debian image

[Damien Zammit]

Hi there!

I am interested in getting more driver support into the Hurd.

I started by rebasing/compiling the PCI arbiter patches and documenting
the steps required to make it all work on the stock Debian disk image.
Note you might need to extend the disk image to get more disk space
before attempting this on the actual disk image.
(I had to repartition mine which was a bit fiddly).

Please see below and attached tarball with all rebased patches:
Please note that I reconstructed this document after I completed it.
It's more a set of pseudo instructions - not just bash commands.

I hope this small effort is put to good use to get these patches ready
for merging soon before they need another rebase.

## hack makefile to install to /sbin and headers to /usr/include
sudo apt-get remove pciutils

# Finally, build pci-arbiter and install it

# Magic
sudo mkdir -p /servers/bus/pci

sudo /sbin/lspci -A hurd
## nice output
