What I was getting at was that if you'd had it working with a 2.4 kernel then you might have a better idea of how to proceed with 2.6. Basically, smart link have a driver for their modems which works(?) with some implementations of their hardware and kernel 2.6 but not for mine. If you knew for instance that all versions of their earlier drivers worked then you'd be much more likely to find a working version of this version. Plus in the interim, you could always keep a working 2.4 kernel, and modem setup just for downloading those big unwieldy files that are difficult to transfer onto your linux partition.
Here's where smartlink keep their drivers anyhow.
