The lower the black hole mass, the higher the temperature of the Hawking radiation. This prediction is based on approximations that seem warranted as long as the black hole has mass $M >> M_\text{planck}$. No-one knows what precise phenomena occur when the black hole mass approaches $M_\text{planck}$. Drawing conclusions on the $M \to 0$ limit based on GR is certainly not justified.
