Does anybody know what exactly happens when I change the boot drive using the System Disk utility? Is there any way to make the same changes on the OSX command line?

Here's how
Here is a link to a thread at macosx.com where I give an extremely detailed explanation of how to set up a CLI script to switch startup disks.
I'll just give the hilights here: Switch the system disk control panel to boot into OS 9. From the terminal, run nvram -p > OS9 This dumps the nvram (pram to some) settings into a file called OS9. Switch to OS X booting with system disk, then repeat the nvram dump into a different file. Use the diff command to inspect the differences between them. You will see that a specific value of a specific boot-variable neets to be changed to get the machine to boot one way or another (differs from machine to machine). You can then use the nvram command to set this boot-variable to the proper setting, or script this. Everything is explained in a lot more detail in the link I give at the top. Zach
good hint!
(This will be very helpfull, when I can start the System Disk utility again.
system disk freeze
Try running the OS X disk utility, and if that doesn't find anything, try booting into 9 from a CD and running the disk utility there -- or better yet, norton (the new version that doesn't muck up OS X stuff!) or techtool.
