While I agree they should update their kernels, I suspect none of those
modems do. I am however certain that none of them are running an
SMP-enabled multiplatform kernel on an ARM1136r0!

Are these actually ARMv6? Most ARM11 cores you'd come across
in practice are ARMv6K (ARM1136r1, ARM1167, ARM11MPCore),
in particular every SoC that has any mainline support except for
the ARM1136r0 based OMAP2 and i.MX3.
