Sorry for the typo... i was refering to the correct EPSG...
That was just what I needed... though I got another different workaround for
it that got it solved =)
That had nothing to do with my app haha... (though I might think to getting
back to solving this through the app... cause I think it would make things a
lot quicker...)

The problem was at the integration between PostGIS and Mapserver... I solved
it changing the DATA parameter of my layers at the generated .map file...
(Mapserver was reading 4326... while PostGIS was delivering 900914... that
was why I was trying to force PostGIS to get 4326... actually letting the
user choose which to enforce)
Right now... I'm letting ogr2ogr assume the Spatial References... so that
makes me manually change the .map files...

I'll see if a can get any workaround that flows better...

I'm hearing suggestions =)

Again... thanks!
