Redmine

As of today, one can't package redmine for debian, due to rails version mismatch.
I'm trying to get debian to package a compatible rails version into their repository...
for now debian has rails 2.1.0, which doesn't work with redmine (i tested for myself),
and the required 2.1.2 version for redmine is not listed as a milestone :
http://rails.lighthouseapp.com/projects/8994-ruby-on-rails/milestones
so it is kind of difficult to convince the rails package maintainer to package that version.
so my questions are :
1) does redmine works with rails 2.1.1 ?
2) will redmine 0.9 work with rails 2.2 ?
3) is there any prospective on rails 2.3 compatibility ?

i'm not much of a railer :)
