I know how to use Google, too. I hoped that your problem could be fixed 
through the kernel command line, but I just confirmed that this is not 
possible. No need to bash me for that. :-(

Kernel drivers live inside the kernel source tree, so changing a driver 
soure file is equivalent to changing a kernel source file itself, which 
is the same as changing the kernel.

Whether you compile a driver as a kernel module (i.e. a separate file 
which gets loaded into the running kernel at runtime) or not (i.e. 
integrated into the kernel binary itself and loaded at kernel 
initialization time) is a matter of preference. This is what kernel 
configuration is all about: [Y]es, [N]o, or [M]odule.

I would avoid using kernel modules and build everything which is 
integrated (i.e. not hotpluggable) into the kernel. Hotpluggable stuff 
(USB drivers) is a case-by-case decision.

I don't know what to think of your knowledge. On one side, you seem to 
know quite a bit, on the other side you behave like you have no clue of 
what you are doing. It's hard for me to know what I can trust you to do 
correctly on your own given a few instructions and where hand-holding is 
necessary.

Just on a side note, mailing lists are not live communication channels. 
They are archived, and in a few weeks nobody cares about your endeavours 
to get things to work. But people might care about facts and solutions 
to problems. Please keep focused. Searching through 40+ mails of chat is 
a pain for anyone not living in the same time zone. Especially when 
there is no useful information /at all/.

IRC is the perfect medium for live discussions, step-by-step 
hand-holding, "you can't build a kernel, but I can build one for you and 
you can test it" setups and similar things. But please don't spam the 
list uselessly.

Best Regards,
Sebastian,
going to bed now (4:30am local time).
