Or is that the CKDIV8 fuse ?
According to the datasheet your technique overrides the CKDIV8 fuse. So whether or not it is set, you can change the prescaler to something else.

Okay, I think I understand it. The fuse CKDIV8 presets the value 0x03 in the CLKPS register and thus sets a clock prescaler of 8.

The old ATmega8 was already able to use TIMER2 with 32,768kHz crystal. But a lot of the clock part is improved in the ATmega328P.

I hope so. It's difficult to tell right now. :)

Sorry that I'm a bit late. I was having problems with getting your first code-try to work and it still consumed a lot, as if the code was indeed not working. The second code worked but LCD did not work. I still appreciate your (and others) help, Nick.
I got it now working on the mentioned MSP430 series chip (MSP430G2553): http://forum.43oh.com/topic/6198-geiger-counter-with-ti-launchpad-msp-exp430g2-msp430g2553/
