The latest installer.coff from cap.anu.edu.au/pub/linux-pmac should 
fix this problem

It's a bug in the installer that hasn't been worked out yet.  You can
get around it by pressing [command-F2], typing any character, hitting
return, and return to the installer by pressing [command-F1].  You'll
have to do this each time it hangs like that.  I'm not sure why it does
it, but you should be able to install everything.
 
addendum:
The following is from a posting to the linux-pmac mailing list from

I'm guessing this is a SCSI driver problem. Typing unknown commands
and hitting enter causes the machine to search the drive for that
command. Report what kind of SCSI controller you have, whether you
have two controllers, what controller the drive you were installing
onto is on, what controller the CDROM drive is on and any other info
about your hardware - better yet, supply a patch :)
