Oh, niiiice!

Slight improvement for the second line:
   '/<p>((<([^"\'>]|"[^"]*"|\'[^\']*\')>)*[[:upper:]])/',

This should properly handle things like
   <img title="foo -> bar">
;-p

One other generalisation should be done IMHO: Some tags should prevent 
capitalisation. I can imagine stuff like <h1>, ... <h6>, <ul>, etc.

Not sure how that could be best done though; things that spring to my 
mind are "lookahead assertion" (which may be entirely unnecessary 
though), "do we look for tags that we want to skip, or do we look for 
tags that we *don't* want to skip?", and "the tag list should be 
separated out into a separate PHP variable, so that people who aren't 
regex experts can make use of that".
