Downgrading to 10.6 without losing data

[-BigMac-]

Hi guys,
i searched and couldnt find a particular instruction thread.
I want to downgrade down to SL from dev. 3 BUT.. i would like to do it without losing my bootcamp partition, and the ability to use the bootcamp partition.
Would that be possible?

Thanks a lot
