  The nonrelativistic annihilation of Majorana dark matter in the Sun to a pair
of light fermions is chirality-suppressed. Annihilation to 3-body final states
$\ell^+f^-V$, where $V=W,Z,\gamma$, and $\ell$ and $f$ are light fermions (that
may be the same), becomes dominant since bremsstrahlung relaxes the chirality
suppression. We evaluate the neutrino spectra at the source, including spin and
helicity dependent effects, and assess the detectability of each significant
bremsstrahlung channel at IceCube/DeepCore. We also show how to combine the
sensitivities to the dark matter-nucleon scattering cross section in individual
channels, since typically several channels contribute in models.
