No problem... But Iīm still deciding whatīs the best strategy. Iīve tried two
approaches:
* distribute a .o file with the code which requires a small patch to the
Makefile, so that it gets linked in (the current method)
* build a separate module that acts as a īpluginī to the pwc driver.
Both methods have their pros and cons, and one common problem: users donīt
read documentation :-(
The first method is a bit more difficult for the average Linux user (most can
find their way trough the kernel menuīs, but patching the tree is a bit
different, and scary). However, it usually works best.
The second suffers from 2 problems: kernel module versioning, and the kernel
version. The first I solved by exporting symbols from my code with
EXPORT_SYMBOL_NOVERSION and using wrapper functions for kmalloc() etc. The
second is a lot more irritating: unless users use exactly the same kernel
version, modprobe complains about kernel versions long and hard. And with
2.4.* itīs not possible anymore to build īversion-lessī modules like with
2.2.* (#define NO_VERSION does not have any effect anymore), unless I
overlooked something.

Very well, I will prepare a patch. Any particular kernel version you want it
against? I usually do not run -ac kernels... (plus, in this case it would be
rather trivial since itīs a self-sustained module)
