You don't need it to match your kernel - just use insmod -f to install the module. I'm using the module (I assume you mean pwcx-i386.o) on several kernel builds on Redhat 7.3 and on Redhat 8.1 RC5 - works perfectly.

CONFIG_MODVERSIONS Usually, modules have to be recompiled whenever you switch to a new kernel.

All the software needed for module support is in the modutils package (check the file file:Documentation/Changes for location and latest version).

If you are going to use modules that are generated from non-kernel sources, you would benefit from this option. Otherwise it's not that important.

Doesn't help much, at least with the default distributions. The pwcx-i386.o module itself worked for me when insmod -f without any problems on several kernels. I also tested it on kernel 2.5.61 and it worked without a problem with insmod -f And yes, I know it's dangeous, but: 1. I don't have the source code, and Philips don't want to release the code (it's not theirs) 2. It gives me the BEST driver for my cam - almost all the features of this cam works (only the button on top of it doesn't, yet).

Did you (or anyone else) consider reverse engineering the driver? is documentation available? Well, I don't know how much (if any) got to reverse engineer the algorithm inside. There are no documentation available, as the Linux driver author signed an NDA before writing the driver, and he maintain it, but he cannot release for every single kernel a new module...

If the source was available, then there wouldn't be any issue of insmod -f ... No, the source is not available, nor the documentation for the compression algorithm... It's not that you can't use the cam without this module.. sure you can, but you'll loose your frame rate and capture size (the cam can capture 640x480 15 fps, and up to 1280x1024 in 1 fps), so you'll need to load the first open source module which activates the cam, and then the binary module which enhances the driver..
