Ok, I have it now. On Dennis CC the game starts on the 
wrong bank, so my code:

    BIT $1FF9
    JMP MainGame

    .byte   $FF, $FF, $FF, $FF
    .word   SwitchToBank1
    .word   SwitchToBank1
    .word   SwitchToBank1

would force it back to the intro bank. Now on the other 
bank, it looks like this:

    BIT $1FF8
    JMP StartScore
    .byte   $FF, $FF, $FF, $FF  ;           addresses 
for bank-switching (do not use!)
    .word   start
    .word   start
    .word   start

And when _starting_ the cartridge on "StartScore", the 
initing code isn't executed.

Well, that explains the problem, but what would be a 
proper solution?

If the RAM content is more or less random on startup, 
how could I ever tell wether I just switched power on or 
if I'm really performing a BS on purpose?!?

(BTW: If frying would only happen on BS cartridges I'd 
say: Yes - that's it! :-))
