ipcop probably uses the program "modem_run" to upload firmware from
userspace (the linux 2.6 driver does this itself). I quickly hacked
modem_run to do the extra initialization that the 2.6.19 module does
(see patch below). This compiles but is otherwise untested. Please
let us know if it helps.

I don't know. Try extracting the firmware from ZZZL3.012 and using
md5sum (for example) to see if you get the same files.

The modem_run changes may also help when using your existing
firmware. However the firmware I sent comes from the "extended
reach" driver, which is designed for long lines, so it may work
better.
