peter> What on earth is the locator stuff for? Why can't you use plain text?
peter> How does 'iobase 0x280' become '640,0,0,0,9,-1,-1,0,1,0'??
This should be changed in the future.
I would say for this point "Yes, there are weaknesses
still, but that is because it isn't quite finished and is evolving still."
I don't think it impossible to make it work
dconfig load "ne4 at isa0 iobase 0x280 irq 9"
dconfig unload ne4
We have just made it work, before making it look cool.

Yes, it does seem cool. But don't you think it even better to simply
tell the system that I want pcic on pci not knowing the
filename (whether it was split into three files, or just one file)?
# dconfig load pcic? at pci?
