The problem is in the precompiled versions of these products.


to solve:

Istall it from CD.
get and upgrade kernel to 2.2.12 and pcmcia to 3.0.14 at least.(its a
boring work! take a look on the HOW-TO's Kernel and PCMCIA)

After that, everything will work.

I found these problems even using distributions with these levels. I
needed to re-compile them.
