|I was able to USB boot my Quad PowerPC G5 without much hassle and thought I'd share the steps I followed.
1)Format the stick using MBR partitioning.
2)Create a single FAT partition.
3)Mount the Gentoo iso and copy all the files to the usb:
cp -r /mnt/cdrom/* /mnt/usb/
4) Edit the /boot/yaboot.conf file and change the device from 'cd:' to 'ud:1'
5) Insert the usb into the PPC and boot into OpenFirmware using Command+Option+F+O
6) Run the boot command like this:
Yaboot should then load and present the available options, enter G5 to start booting.
Important: Initially I tried with HFS+ and although Gentoo started booting it got stuck since at some point it tried to mount the root partition but couldn't since it doesn't have built-in support.
Hope it helps,
