Doesn't look serious.  init_module() is not __init, but it calls
some __init functions and touches some __initdata.

BTW, I would be happy to see some consistent results from modpost
section checking.  I don't see all of these warnings (I see only 1)
when using gcc 3.3.6.  What gcc version are you using?
Does that matter?  (not directed at anyone in particular)

Patch below fixes it for me.  Please test/report.

Fix section mismatch warnings:
WARNING: drivers/net/ne.o - Section mismatch: reference to .init.text: from .text between 'init_module' (at offset 0x396) and 'cleanup_card'
WARNING: drivers/net/ne2.o - Section mismatch: reference to .init.text: from .text between 'init_module' (at offset 0x483) and 'cleanup_card'
