Sadly Macs coming with Mac OS X 10.X.Y can't be downgraded to a previous version of the OS, like Mac OS X 10.X-1 or Mac OS X 10.X.Y-1 for example, so you can't even downgrade form 10.6.2 to 10.6.1 if the machine came with 10.6.2.

Maybe there is a hack around, you can have a look at MRoogle.

Generally speaking the lowest version of OSX you can run is the version that came with your mac. If it had 10.6.1, then there's no way for you to load 10.5

I have been able to install os 10.5.6 on a new MacPro ordered March 2010 shipped with os 10.6 by booting from a set of MacPro installer media from another similiar, but earlier model of a macpro. the installer restore dvd media has 10.5.6 on it. from the retail 10.5.6 dvd it hangs at the white screen when booting from this media. the only way I could do this successfully was to boot from the 10.6 dvd, using disk utility, format the hard drive. booted from the older macpro installers with 10.5.6 and the install went without a hitch.

good luck,
