open-source driver question

Hi, I'm a linux guy and have used netbsd, openbsd, freebsd etc in the past but never tangled with the kernel or drivers outside of Linux.

My mother has fried her ethernet port on her iMac (G4 I think); I recently sent her a silicom USB U2E (usb 2 ethernet) dongle which is evidently not recognized by OS-X. This device works with most linux distros out of the box, and uses the "kaweth" driver which is available on sourceforge. The driver page says it's POSIX compliant which makes me hopeful but I don't know how to proceed.

I'm comfortable with building and installing modules, or even rebuilding the kernel if that's necessary, but I don't know where to start with MacOS. Could someone point me to a resource, or if this driver is already implemented and just needs the VID/PID added to a config file somewhere (or some other trivial step), point me to that?

Thanks for your help.

Stephen

NAME

       ntwdt - Netra--based application watchdog timer driver

SYNOPSIS

       /dev/ntwdt

       The  ntwdt  driver is a multithreaded, loadable, non-STREAMS pseudo driver that provides an application with an interface for controlling a
       system watchdog timer.

       The ntwdt driver implements a virtual watchdog timer that a privileged application (Effective UID == 0) controls via IOCTLs.

CONFIGURATION

       You configure the ntwdt driver by modifying the contents of the ntwdt.conf file.

ERRORS

       An open() fails if:

       EPERM		       Effective user ID is not zero.

       ENOENT		       /dev/ntwdt is not present or driver is not installed.

       EAGAIN		       /dev/ntwdt has already been successfully open()'d.
