HELP!!! : Can't start database - Rollback Datafiles are missing -

Hi guys, I need help!
At this moment, it doesn't matter how I messed everything up, but Development server is down.
Had to recover operating system with a two month old backup. Oracle motor resides in the MkSysB backups, so some files where replaced, some datafiles where lost, and control file is mixed up. I can mount the database, but can't open it because rollback datafiles (and filesystem) where lost in the crash. Had to rebuild the filesystem, but I'm not able to rebuild the controlfile due to datafiles errors on the rollback tablespaces.
I tried, with no success, to rebuild the controlfile leaving out the rollback datafiles, but that didn't work. What am I missing here???
Is there a way I can recover the database without having to rebuild it? I do have a tape with a full backup (from last weekend), and I'm leaving that as a last resource. I also have full export from yesterday, wich I can download too.
I made changes to the physical structure of the database today today, and would have to rebuild many filesystems to download that tape....but I will if I have to.
I would appreciate any help you can give me!!!! please! (I've been on this matter for 6 hours already!) thanks,
Vero.
