No, and no. Try these patches (apply in this order, may need some hand-patching to apply to the current 2.4.21-pre source):
http://www.amelek.gda.pl/linux-patches/2.4.20-pre9/00_parport_serial http://www.amelek.gda.pl/linux-patches/2.4.20-pre9/01_netmos
Please test - I'd like to know if it works for you. It should - I have 3 such cards in 2 servers, running patched 2.4.20 kernel in production use for 3 months now (mainly serial ports used, but 2S1P cards were cheaper than 2S cards...). Attempts to submit the changes have been ignored, so I gave up...
NetMos support was already in early 2.4.x kernels, later removed:
* parport_serial.c: Remove NetMos support, since it causes problems for some people.
No idea what exactly these problems are, who "some people" are, why NetMos support was not simply made a config option conditional on CONFIG_EXPERIMENTAL, and why the link order bugfix (separate patch, which only fixes an obvious bug) has been ignored too.
Perhaps you will have more luck than I did - test your card with the patches for some time, if it works try to submit the patches again...

I don't use devfs, so I never had this problem.
Hope this helps, Marek
