Собрал драйвера 4.3.1 под Linux 2.4.20.

Загружаю, получаю:
Protocol binder loaded
<Cronyx-Tau-PCI> at 0xdd110000 irq 16
Cisco protocol loaded

Пишу: sconfig -a chan0
В ответ:
chan0 debug=134534992 idle extclock syn=1108546764 dpll=off nrzi=on invclk=on invrclk=on invtclk=on unfram=on use16=on crc4=on higain=on monitor=on phony=on scrambler=on loop=off ts=3-4,7-8,11-12,15-16,19-20,23-24,27-28
В логи ядра пишется:
cp0: unknown ioctl type:x nr:25 size:4
cp0: unknown ioctl type:x nr:34 size:4
cp0: ioctl: SETDIR
cp0: ioctl: SETSCRAMBLER

Пишу sconfig chan0 cisco
В логи падает:
cp0: unknown ioctl type:x nr:14 size:32
cp0: ioctl: GETMODE
и настройки не меняются

В какую сторону копать ?

в ifconfig'е ничего нового - eth + lo
