While on the subject of adding get_xxx methods, another handy method 
would be to get the current graphics driver that is set with 
set_gfx_mode()'s 'card' parameter. If set_gfx_mode() is called with one 
of the magic drivers such as GFX_AUTODETECT, there is currently no way 
of knowing what driver is installed. The function get_gfx_mode_list(int 
card) requires a real driver and not a magic driver for the 'card' 
paramater, so if you want to know what resolutions are available using 
the current driver, you would have to set the graphics mode without 
using a magic driver and remember the driver-ID.
