Hi!

I guess version check is needed, but this is excessive:

Apr 5 07:33:16 amd kernel: udlfb: version magic
'2.6.34-rc3-00345-ge8240f9-dirty SMP mod_unload CORE2 ' should be
'2.6.34-rc3-00344-g548fc0a-dirty SMP mod_unload CORE2 '

Yes, I played with git and recompiled my kernel in order to get new
module version, but... not even insmod -f works.

Having to reboot every time I recompile the module or play with git
makes modules useless for development :-(.

Disable CONFIG_LOCALVERSION_AUTO?

I don't think so. Essentially you are getting what you configured: an
extremely fine-grained kernel version. It's up to you to decide whether
the benefits of that outweigh the limitations it brings.

Stripping parts of the kernel version for module compatibility checks could
interfere with suffixes explicitly added by distros to specify ABI
compatibility.

Cheers,
FJP
