Thanks, Robert.
tps65217 was the clue I needed. Fedora config has it building as a
module. But the module is not included in the initramfs, so not
available at boot time.
Solution: Either rebuild the Fedora kernel with
"CONFIG_REGULATOR_TPS65217=y" or edit /etc/dracut.conf, 'add_drivers
+="tps65217-regulator"' and rebuild initramfs/uinitrd, gets the Fedora
kernel booting.
Now need to figure out where the power management has gone. I suspect
your kernels have it built-in and Fedora has "CONFIG_XXX=m", so more
module nonsense.
Fedora's 3.13.x might still be missing these:

They should hit v3.15-rcX (fingers crossed)
Beyond that, advanced power-management (suspend) thru the cortex-m
firmware doesn't work outside of ti's v3.12.x branch anyways.
