You're right, but in a laptop using the integrated modem is more
practical, with less stuff to carry, and less power involved. Provided
of course I do it at my own risk, and don't try to rebutt the troubles I
may get into to kernel people, which has more useful things to do, than
following my personal whims.
BTW on my previous laptop I had a Lucent winmodem, whose driver doesn't
fake the GPL license, but which was definitely inferior to the Linuxant
driver, except for the hardware probing stupid implementation.
I'm looking forward for a time when being "Designed for Linux" will be
more rewarding for a manufacturer than being "Designed for Windows" but
till then I must get along with what is available.

There's no *run-time* sign. But I was made aware of that when I
downloaded it from a different source, and I had to agree to a non GPL
license. It didn't originate from kernel group and I'm using it at my
own risk.

Maybe I fail to grasp the full picture, but I'd just have ignored it.
Please remember that they "fake" GPL only at run-time, not when you get
them.

If you download the "generic package with source" either rpm or tar.gz,
you'll find the GPL directory populated. I've checked again right now,
just to be sure. At least, this holds true for hsf modem, which is the
one I'm actually using.

If you're interested, and have time, you may also estimate if they've
implemented in the GPL part all of the critical kernel code (as I had
assumed, maybe naively, from a cursory look to the code), leaving in the
proprietary binaries only the "proprietary" compression/decompression
algorithms, or if they've just provided a minimal wrapper, with all
"real" code proprietary.

It may make sense not to have anything left in the GPL directory in a
binary only .rpm package, because once linked GPL parts cannot be told
apart from non-GPL ones.
