Bug#561099: what about decimal wraparound?

[Thiemo Nagel <thiemo.nagel@ph.tum.de>]

Ordinary users will be affected as soon as the linux kernel version adds 
another digit:
* 2.6.100
* 2.10.x
* 10.x.x

Even today 2.6.30.10 sorts before 2.6.30.9, so anybody who builds his 
own kernel may be affected (not -rc kernels only).
