[wp-hackers] Access the total number of pages of a multipage post or page out of the loop

[Mark Duncan]

Inside the loop get the value of $numpages (global if necessary), and it 
should give you the total amount of pages in accordance with your usage 
of <!--nextpage--> for that post/page.

Tested on trunk, and returns the correct value for a paged post..

Hope that helps.
