Detecting the IRQ isn't the problem. The driver is built for RedHat 6.1
(who has a long history of heavily patching their kernels), and what
you're using is a *hell* a lot more recent.
I was going to suggest "insmod -f", but I see you alreay tried that :)
Since that didn't work, I have to say that you're really out of luck. I
hope you didn't pay much for the modem...
As to why it doesn't work: A good analogy is you're trying to load a
driver for Win95 into WinME - the kernels are waaaay to different for the
driver to load.
In Linux, the driver is very sensitive to the kernel it's being loaded in
to. If someone uses a different compiler from you, or, more importantly,
has a different set of patches from you when they built the driver,
there's a very good chance that the driver won't load.

The driver wasn't loaded.
