That is a difficult problem, as is discussed for the
binary logit/probit case in:
http://www.stata-journal.com/article.html?article=st0063
Fortunately this problem only arrises when you want to compute
probabilities and does not arrise when you interpret the results
in terms of relative risk ratios/odds ratios, so I would advise
you to do just that.
Hope this helps,

This ignores an other problem that is among others discussed here:
http://www.nd.edu/~rwilliam/oglm/RW_Hetero_Choice.pdf
The somewhat excagerated version of my opinion on this is that
there can be no solution to this problem, and one should not waste
their time worying about unsolvable problems. (It is however still
good to know the limits of what one is doing)
