Comment 237 for bug 621265

And another one:
http://piliszek.tk/patch%232/linux-image-2.6.35-25-generic_2.6.35-25.44_i386.deb

Note that they replace each other. I had not found any info about how to change the version before I started compiling them.

But I can assure you that the next time I will upload a patched kernel, it will have custom version.
