I also have a target board consisting of an ARM processor and Intel
Strataflash with an embedded Linux OS running kernel 2.2.14.

I'd be surprised if it doesn't - my current code isn't being tested on 
anything _but_ 2.2.14/StrongARM.

That's fine - you can use that and it _should_ apply cleanly.

They're definitely in the patch. Did it fail to apply them for some reason? 

The {get,put}_module_symbol() patch is also available separately as 
mtd/patches/put_module_symbol-2.2.1x.patch. Try applying that and see what 
happens.

It's easy enough to do it by hand. Add __MOD_INC_USE_COUNT(mp) in the right 
place in the existing get_module_symbol() routine, and add the new 
put_module_symbol() routine from the patch. Then add the prototype to 
module.h and an export entry to ksyms.c
