We had to adapt the lfg file for lm (other fonts are ok) so i'll make an 
update.

If you're in a hurry, in lm.lfg:

         parameters = {
             FractionNumeratorDisplayStyleShiftUp = 600, -- used to be a 
function
             NoLimitSupFactor                     =   0,
             NoLimitSubFactor                     = 900,
          -- AccentBaseHeight                     =   0,
             AccentBaseDepth                      =  50,
         },

can be adapted.
