boot1.txt is just the boot script, which OFW (Open Firmware) uses to load boot1.elf
boot1.elf is the real boot "loader" (if I have figured this out correctly),
so I suspect we need to look at that, and figure out how it decides which partition to boot from.
Look at /usr/src/sys/boot/powerpc/boot1.chrp/boot1.c
for the source.

Sorry, I do not know the answers to those questions.
