If most of your traffic arrives in on your English pages and then they have to click to get it into the Portuguese site then you might be ok.
What other languages is your site in?
Just how dependant are you on needing to run you Adsense code on these Portuguese pages or site?
Just how similar is Spanish & Portuguese anyway? thinking about what Jenstar said about their mediatbot reporting back to Google that the language is not recognized, if Spanish & Portuguese are similar (Forgive my ignorance here if they are not) then maybe it will not trip any switches.
One of my sites is an Open Directory mirror and I have a check in the code to make sure I invoke AdSense only on 5 supported languages (English, Spanish, etc).
For other languages, I include my 'alternate ads' page instead - I am using it to cross-promote my other sites and forums,
via randomizer.
A few extra lines of code bring peace of mind.
