Ok, now I understand your problem, but honestly, in such a situation I 
believe that it is better to chose a relevant projection, reproject the 
grid and then just use resolution^2 as cell size...

But since you already have gone down the route of calculating cell size 
in r.mapcalc, I guess you really wanted to do it in latlon... ;-)
