Could this be a result of the switch from emulated floppy bootable CDs
to 'no emulation' bootable CDs that happened with between the 4.x and
5.x branches?

If you can do a "make release" to create you own .iso images, try doing
it with the EMUL_BOOT variable defined, which will generate the .iso
images with the emulated-floppy boot code.
