I poked the git server at freedesktop.org, where poppler resides, and found what
appears to be the series of commits that removed QT3 support (five on Jan. 16, 
2011, plus an outlier about a month later).  Full diffs for these commits are 
stored, so depending on how much the codebase has changed in the past year, 
we may be able to just revert them.
