yeah, Im in the same situation, powerpc based mac hacked iPod no way to rearrange the icons, ok what you need to do if you are in this situation is either help, or sit back relax and wait for other people to do the work. I'm helping, in my opinion the best way to rearrange your icons on the iPhone is an application called customize, currently this application has within it rSBT. Customize works fine on the touch but rSBT doesn't, when you click it it just reboots your iPod and nothing happens. rSBT is the app that let's you rearrange your icons, it will let you have any amount of icons you want on your dock (which is sooooo helpful) and any amount you want on your springboard (the place where the other apps are) which would just adjust the size bigger or smaller depending on how many you want. So what I would do if I were you is go to this website:

and ask him what you can do to help. Eventually he will fix it but the more people to help the faster it happens.
