I've upgraded to 2.4.7 without any problems. 

Regard to the above, that is, moduler ReiserFS, its not really an issue, as 
compiling into the kernel hasn't caused any problems.

Just a little suggestion. Is it possible to offer "kernel binary upgrades" 
every other major release, for example, it shipped with 2.4.2, hence, the 
next upgrade to be release, 2.4.4 then 2.4.6 then 2.4.8. I can compile 
everthing however, I know a couple of people too scared to get down into the 
nitty gritty of Linux and compile their own kernel.
