This is not a stupid question, I'm glad for any hint. However I did compile 
the generic module before.

Now I removed two slaves and it works! I readded them and it still works. 
Yesterday I tried the whole day to no avail. I'll let you know if it works 
tomorrow. Right now I have no idea why it works or why it didn't. Maybe there 
was a physical problem, and the native driver did not care.

On a different machine there seems to be a problem with mixing a 64 bit kernel 
with 32 bit userspace, but that won't be limited to the generic driver, and 
this setup is not so important.

A third machine where the generic driver failed is not available to me 
anymore. The native e100 driver worked on the same interface.

Thanks for your time,
Fabian
