You were quite right. There is a define in hisax.h where I4L_IRQ_FLAGS is
set to 0. If I change this to SA_SHIRQ it works! At least the card can be
configured. I'll check if I can get an internet connection over ISDN as
soon as I'm back home.

I'll send a note to the maintainer of the hisax driver.

Thanks for the help.
