No solution yet :-(, only more questions...
It looks to me that the plugin is intended to work when the lowres
raster extends the highres raster only in one direction. In your case,
the 1 degree SRTM tile you are using totally contains the USGS 1 meter
region.
To test this I would try to clip out a section of the SRTM:
# Set the computation region to the highres raster, then extend only in
one direction
g.region -p rast=USGS_one_meter_x39y445_IL_12_County_ChampaignCo_2008
g.region -p w=88:20:00W
# Now clip the SRTM to this new region
# But use the coarse resolution
g.region -p res=0:00:01
r.mapcalc "n40_w089_clip = n40_w089_1arc_v3"
# Now try r.mblend with this clipped SRTM
r.mblend high=USGS_one_meter_x39y445_IL_12_County_ChampaignCo_2008
low=n40_w089_clip out=blend
Please report back if this helps (or not...)
