[X4U] Rolling back to 10.4.7

[Robert A. Virzi]

Okay, 10.4.8 pretty much s*cks.  IE no longer runs, Spotlight privacy 
is flaky, and I am seeing crashes in Eudora and SuperDuper that I've 
never had before.  SD tech support says this is a know 
apple-introduced bug causing their failures.

So what's the process for backing out 10.4.8 to the earlier release? 
10.4.7 was stable as can be for me.  This is on a macbook pro if that 
matters.
