Ahh! Resizing ext3

[a monkey]

I'm having a terrible time resizing my ext3 filesystem so that I have 
room to test out a few other distros, and maybe install Mac OS X. I 
tried the parted bootdisks, I tried a Gentoo LiveCD, I tried 
*everything!* No matter what, I kept getting an error about a strange 
partition map, or something. If anybody has figured out a way to resize 
their filesystem on their PPC, please let me know.
