This module contains versions for both x86 and PowerPC processors. The module is cross-compiled for PowerPC, so anything might go wrong. However, so far all feedback has been positive.
Installation of this module is very simple; copy the correct pwcx.o module (pwcx-i386.o or pwcx-ppc.o) to /lib/modules/usb/pwcx.o, and run 'depmod -a' once. After this, it should be possible to load the module on ANY kernel where the pwc.o module has been built or loaded (well, provided it's running on one of the supported processors, of course).
There is one small catch, however. The modules are compiled on 2.4.15/2.4.16, and with 2.4.* kernels it's impossible to create 'version-less' modules, so you must use 'insmod -f' to load the module ('modprobe -f' works too). Insmod will complain, but it will work (I have run and tested this module on 2.2.18: worked like a charm).
The module does not take parameters. Also, you must load it after the pwc module.
It's currently not possible to link this module into to kernel bzImage, so you must enable module loading. In addition, turn off module versioning in your kernel (by default, it's on).
