This is a total hack that I have not tried so you might want to have a
laugh.

Could you set zoom to max zoom for the closest satellite view that is
available for any location. Once at that zoom level, test if you are
getting an image location for the first img tag starting at the
map_canvas div such as 
http://khm2.google.com/kh/v=48&hl=en-US&x=481912&y=315155&z=19&s=Gal

If you do, that means there is satellite imagery available.

If you get an img location of 
http://maps.gstatic.com/intl/en_us/mapfiles/transparent.png
then zoom out 1 more time and try the test again.

Good luck!
