The global initialization code should thus return -ENODEV and
thus eradict the device ? Right now (1.3.37) it returns "1";
Same with slip_init_ctrl_dev(), which now returns ENODEV.
Oh by the way, I have NEVER been able to reproduce this
phenomena at my laptop.. I would like to try to create
it, and thus be able to detect it -- and fix, naturally.
(My laptop runs 1.3.35 with APM, and with PCMCIA 2.7.3.)
Please send me your current kernel's .config, if I could
reproduce the phenomena with it.

Umm... I have SLIP as a module, you as a static device ?
(It should not matter though..)
