I have no particular experience with the mkgmap application, but from using cgpsmapper for making maps I know that using too large an area will often fail.
There is however a simple way of combining individually created non-overlapping maps into a larger map, using a program called gmaptool ( http://www.anpo.republika.pl/download.html). It is a simple command line application. I have used this successfully to combine maps created from OSM data into a larger file.
