Possible Kernel patch/hack needed, for use of Ambicom BT2000 CF adapter...

[Martes G Wigglesworth]

Thanks for the response.  I am just starting into the C-programming
stuff.  I have some good books, but I won't be taking my C++ class until
the fall, so I am just winging it currently.  Are there any good howtos
on what is needed to patch as you have indicated?  I really want to get
into this stuff, however, I am not well versed in programming operating
systems, yet.  Any hints?  I have downloaded the Architecure
Manual/Handbook, for FreeBSD, but I was hoping for a no frills
quick-start, for someone like myself.  I have not found good information
on what in actually involved in patching the kernel.

Thanks again, and will be waiting for that patch.
