Sure, duplicate that stanza and change just the "root" line to hd1 in the 2nd, 
hd2 in the third, etc. And maybe change the title to remind you which is which. 
The boot from a stanza which matches where the BIOS maps your USB drive.

Pedantic note: I bet you can also do this by switching the mapping with the map 
directive, but that's way harder to explain.

title F11_disk0 (2.6.29.4-167.fc11.x86_64)
	root (hd0,0)
	kernel /boot/vmlinuz-2.6.29.4-167.fc11.x86_64 ro root=UUID=e73e50db-2420
-4792-a347-3e15ed38c5b9 rhgb quiet
	initrd /boot/initrd-2.6.29.4-167.fc11.x86_64.img
title F11_disk1 (2.6.29.4-167.fc11.x86_64)
	root (hd1,0)
	kernel /boot/vmlinuz-2.6.29.4-167.fc11.x86_64 ro root=UUID=e73e50db-2420
-4792-a347-3e15ed38c5b9 rhgb quiet
	initrd /boot/initrd-2.6.29.4-167.fc11.x86_64.img
title F11_disk2 (2.6.29.4-167.fc11.x86_64)
	root (hd2,0)
	kernel /boot/vmlinuz-2.6.29.4-167.fc11.x86_64 ro root=UUID=e73e50db-2420
-4792-a347-3e15ed38c5b9 rhgb quiet
