I have 2 comments:
1) You can probably get those with the new -margins- command in official 
Stata.
2) The easiest sollution is not to use marginal effects but odds ratios or 
relative risk ratios. The whole problem that -inteff- tries to solve 
doesn't exist for those measures.

Hope this helps,
Maarten
