OK, i've sloved this. Extensions are now initialized before 
_al_ogl_create_backbuffer() gets called.
The attached patch includes your patch and my fix. It works fine on my card, 
which supports NPOT, but if I "disable" NPOT support with 
"!ogl_dpy->extension_list->ALLEGRO_GL_ARB_texture_non_power_of_two" the text in 
exnew_bitmap_target does not display properly.
