Hi Ulrik,

has the variable infinity got any special value? Using Infinity instead leads
to no Problem in version 5.1:

In[1]:= $Version
Out[1]= "5.1 for Microsoft Windows (October 25, 2004)"
In[2]:= Limit[(-(2^(n - 1)*M)/(n!*L^(n - 1)))^(n/2), n -> Infinity,
  Assumptions -> M > 0 && L > 0]
Out[2]= 0
