The hadronic mass distribution in semileptonic B-meson decays can be used for
extracting the charmless part and thus determining the |V_ub/V_cb| ratio. We
take into account first-order perturbative as well as non-perturbative QCD
corrections. The sensitivity to model assumptions is studied and an estimate of
the remaining uncertainties is performed.
