Eh, unfortunately ASTER and MODIS data _are_ supported for geolocation in
gdal, so r.in.aster is able to manage a few products directly through
gdal_warp. That's not the same for MISR where a few additional metadata also 
need to be used to extract the true radiance and BRF fields and so on.
I think the most clean and effective approach is specializing the HDF4 driver for
MISR products in GDAL...
