O.K., here is a patch that adds support for devfs to raw.c. It
precreates /dev/raw/raw* nodes for all available minors; I do not
particularly like it, but raw command needs existing devices to get
minor number from; also, strictly speaking, all of them do exist as soon
as driver is loaded.
Is it acceptable from devfs point of view? It seems to work here.
Patch is against 2.4.16-4mdk
Guillaume, could you test it?
