Soft modem in the ibook 2.2

Hello ML,

I hope I am not too off topic or FAQ with the post here.

I am trying to get the soft modem in my ibook 2.2 (900 MHz, G3) working
for quite a while now, and I am absolutely at a loss heere. 

I am wondering if someone on this list got his/her modem in this ibook
running with one of the drivers provided by linuxant. 

scanmodem and friends didn't detect any modems on my ibook, though I
believe I found a post some time ago, where a guy stated he had this
ibook2 modem running successfuly with linuxant drivers. (I might be as
well hallucinating here, maybe I am trying on this for too long now ...)  

However, the only driver I found, which shipps the binary part for PPC
is hcfusb, which doesn't recognise the modem as a interesting one.
(dmesg output reads: "not the one we are interested about)

find /proc |grep modem even outputs:

| /proc/device-tree/pci@f2000000/mac-io@17/i2c@18000/i2c-modem
| /proc/device-tree/pci@f2000000/mac-io@17/i2c@18000/i2c-modem/name

| /proc/device-tree/pci@f2000000/mac-io@17/i2c@18000/i2c-modem/linux,phandle

Does such a thing like a i2c modem exist?

If so, does anybody have an idea wherre to look for linux 2.6 drivers
then?

Thanks very much for any enlightening replies about this. :-)
