Before I comment, I want to make sure we're talking about the 
same thing. :)   When I did my upgrade, I looked at my disk usage
information in the EUA's option called "QB020" and it looked 
something like this:

                                                    Estimated Storage

    Storage used (M) . . . . . . . . . . . . . . . . :     4559.72
  Required IMPI system capacity (M)  . . . . . . . . :   4813.21

As you can see, it says that I don't have sufficient storage.  The IMPI
(CISC) storage required is below the amount of storage that I have, and
the PowerPC (RISC) storage required is above the amount.

To me, it appeared that the reason it said I wouldn't have enough storage
seemed to be that it assumed that I was using the same disks on the RISC
machine as I had on a CISC machine.  (Does anyone actually do that?!)

In reality, my RISC machine had 5 times as much disk space as my CISC
machine -- the 6gb wasn't even close to filling the disk.

So I went ahead and did the upgrade -- I didn't have any problems.  It
only needed a tiny amount of additional space on the CISC machine (for
the QUPGRADE library)  I had absolutely no problems with disk space.

Hope that helps...
