2015-10-22: I got Lubuntu 14.04 working on that PowerBook G4, read more details at Ubuntu Forums discussion.
Copied here from http://ubuntuforums.org/showthread.php?t=2294789&page=2&p=13360635#post13360635 after I got it working.
First I downloaded Ubuntu PowerPC alternative install, installed in text mode, setup static IP because my DHCP didn't work. I did setup partitions as they were from previous install, dual boot with Mac OS X.
Then I started in boot menu l = linux, and then "Linux single nomodeset" to get to console.
I installed all updates.
To get ssh access for doing copy-paste commands easier, I did install ssh and start it (it's not started automatically on single user mode):
sudo apt-get install ssh
sudo service ssh start
Compile instructions for nv module are here:

I think source is originally from here:
http://cgit.freedesktop.org/xorg/driver/xf86-video-nv/
Anyway, I have previously downloaded source files as working backup here, with compiled deb package:
https://sites.google.com/site/lauriojansivu/nv.zip
And here is just the compiled deb package, that works as of today:
https://sites.google.com/site/lauriojansivu/xserver-xorg-video-nv_2.1.20-3_powerpc.deb
After installing deb package, add xorg settings to /etc/X11/xorg.conf, I got this info from here:
http://ubuntuforums.org/showthread.php?t=2131644
sudo nano /etc/X11/xorg.conf
There add this text:
Section "Device"
Identifier "Configured Video Device"
Driver "nv"
EndSection
Section "Monitor"
Identifier "Configured Monitor"
EndSection
Section "Screen"
Identifier "Screen0"
Device "nVidia"
Monitor "Monitor"
DefaultDepth 16
SubSection "Display"
Viewport 0 0
Depth 16
Modes "1024x768"
EndSubSection
EndSection
Then blacklist nouveau driver:
sudo nano /etc/modprobe.d/blacklist-framebuffer.conf
And add there at beginning of list add:
blacklist nouveau
And save.
To install WLAN drivers:
sudo apt-get install firmware-b43legacy-installer
Then reboot:
sudo reboot
And boot with l = Linux, and Enter (no boot options)
BTW, if you get black screen when booting in graphical mode, it means that login screen may be visible, so just write your: username TAB password ENTER to continue booting. But anyway, this is not necessary when NV driver is installed correctly.
