OLPC would like to be able to disable this behaviour through
a custom dracut module. Add a "no_fstab_remount" flag which can be
set by modules that want to disable this functionality.
(Background: having the correct rootfs info in /etc/fstab is a bit of a
challenge for OLPC, because this info is not known at build time.)

Why don't you reuse rd.fstab then? You could add preset kernel cmdline options
in /etc/cmdline in the initramfs.
Just add for your dracut module in install:
mkdir -p ${initdir}/etc
echo " rd.fstab=0 " >> ${initdir}/etc/cmdline
