If anybody is interested, I've made a list of 'most reverted pages' in the english wikipedia based on the analysis of the enwiki-20100130 dump. Here is the list:
http://wpcvn.com/enwiki-20100130.most.reverted.tar.bz
http://wpcvn.com/enwiki-20100130.most.reverted.txt

This list was calculated using the following sampling criteria:
* All pages from the enwiki-20100130 dump;
** Filtered pages with more than 1000 revisions;
** Filtered pages with revert ratios > 0.3;
* Sorted in descending revert ratios.

Page revision is considered to be a revert if there is a previous revision with a matching MD5 checksum;
BTW, if anybody needs it, the python code that identifies reverts, revert wars, self-reverts, etc is available (LGPL).
