As I've already said, if all you need is access to PCI identification
registers, then the data is already present in the device tree. So you
don't need a driver at all. (You might have to walk thru the prom tree
instead of the normal tree, but that is also pretty darn easy.)
Heck, I can supply a bit of code to do the work if nobody else wants to
-- it can't take more than few dozen lines of code. (I've written
device tree walking code before -- and in fact one of my tools in the
afe driver set -- etherdiag -- contains code to walk thru the device
tree looking for compatible devices. Similar tree walking code is
available in ifconfig, though in ifconfig's case it depends on a driver
being present.)
