Bug#404927: udevinfo output for ips driver

Here's udevinfo output from a RHEL4 system w/ the ips driver, courtesy
of Bamm Visscher. You'll notice that this instance also has removable=0.

udevinfo starts with the device the node belongs to and then walks up the
device chain, to print for every device found, all possibly useful attributes
in the udev key format.
Only attributes within one device section may be used together in one rule,
to match the device for which the node will be created.
