Shrug!

Linux was never designed to provide any binary compatibility for modules.
NEVER. Modules are likely to break if you upgrade from one stable kernel
(2.2.15, e.g.) to the next one (2.2.16). Even between kernel compiles with
different settings, some modules may break.
In pratice you may be successful with one module for all 2.2.1x kernels by
sheer luck.

_Binary_ compatibility between a 2.2 and a 2.4 module is almost impossible
unless the module just does nothing ...
