Well, I just tried it. It kinda works, but it seems a bit brittle.

Just after recompiling and rebooting, by chance my system needed a fsck, 
which seemed to delay it enough for it to go beyond the loop count, and 
it failed to load the firmware.

(Even without the fsck, my laptop could hang around indefinitely in 
early userspace waiting for me to type in my cryptoroot password)

Anyway, the second time I rebooted, it was fast enough (without the 
fsck) to load the firmware.

dmesg reported "********** loop count at exit 5" in that case.
