We present submillimeter statistical detections of galaxies discovered in the 5' x 5' Spitzer Early Release Observations (to similar to4 - 15 muJy 5 sigma at 3.6 - 8 mum, 170 muJy at 24 mum) through a stacking analysis of our reanalyzed SCUBA 8 mJy survey maps and a Spitzer identification of a new submillimeter point source in the 8 mJy survey region. For sources detected at 5.8 or 8 mum ( 154 and 111 sources, respectively), we detect positive skews in the submillimeter flux distributions at 99.2% - 99.8% confidence using Kolmogorov-Smirnov tests, at both 850 and 450 mum. We also marginally detect the Spitzer 24 mum galaxies at 850 mum at 97% confidence and place limits on the mean submillimeter fluxes of the 3.6 and 4.5 mum sources. Integrating the submillimeter fluxes of the Spitzer populations, we find the 5.8 mum galaxies contribute 0.12 +/- 0.05 nW m(-2) sr(-1) to the 850 mum background and 2.4 +/- 0.7 nWm(-2) sr(-1) to the 450 mum background; similar contributions are made by the 8 mum-selected sample. We infer that the populations dominating the 5.8 and 8 mum extragalactic background light also contribute around a quarter of the 850 mum background and the majority of the 450 mum background.
