Removing or customizing title attribute in wp_list_pages?

I've noticed that if any HTML tags are used for page naming, those tags are reflected in the title= attribute when returned by wp_list_pages. I'd like to either completely eliminate the title= attribute, or modify it on a post-by-post or page-by-page basis.

I've found a couple of cool plug-ins by Tim Holt that do this, but he says they're not WPMU compatible. Is there any other way of accomplishing this? Otherwise, hovering over menus tends to look unprofessional if, say, emphasis tags are used.

Thanks.

P.S. Alternatively, if a plugin says its not WPMU compatible, what's really involved in making it work? Can it be hard coded for one, specific WPMU blog instance, for example?
