    Yeah, that's what my patchset does -- splits the "hisax" driver into
    multiple smaller drivers. Thus, "modprobe hisax" produces the results
    that you are seeing.

    You'll need to determine which newly-created kernel module applies to
    your hardware. Let me know if you need help with that. The new drivers
    should be in /lib/modules/2.6.25-isdn/kernel/drivers/isdn/hisax/
    provided that you enabled them in the kernel configuration.
