We present the results from a {\it Hubble Space Telescope/ACS} study of thesupernovae associated with gamma-ray bursts 040924 ($z=0.86$) and 041006($z=0.71$). We find evidence that both GRBs were associated with a SN1998bw-like supernova dimmed by $\sim 1.5$ and $\sim 0.3$ magnitudes,respectively, making GRB 040924 the faintest GRB-associated SN ever detected.We study the luminosity dispersion in GRB/XRF-associated SNe and compare tolocal Type Ibc supernovae from the literature. We find significant overlapbetween the two samples, suggesting that GRB/XRF-associated SNe are notnecessarily more luminous nor produce more $^{56}$Ni than local SNe. Based onthe current (limited) datasets, we find that the two samples may share asimilar $^{56}$Ni production mechanism.
