[oe] Compiling a custom kernel module

[Blaine Booher]

Hey guys,
  I am very new to Open Embedded so please bare with me if I make it too 
obvious :).  We are using a gumstix embedded system with open embedded (and 
the angstrom release that gumstix provides).  We would like to use the kernel 
module cp2101 with a usb device.  The default cp2101 module won't work, since 
we have to edit the USB Device ID in the source code.  I'm having a hard time 
figuring out:
1.  How do I 'enable' the cp2101 module in the kernel?
2.  How do I rebuild the kernel, once the source code is edited?
3.  How to I ensure that the module is part of the final build, so that I can 
do a 'modprove cp2101' on the gumstix and have it load successfully?

I have found a few references, including emails on this email list, but 
nothing that explains it in a clear and concise manner (yet, at least).

Thank you in advance,
Blaine
