If you selected some driver in allegro.cfg configuration file, then
set_gfx_mode will not try any other drivers.  For example, setting
'gfx_card = VGA' in allegro.cfg will only try standard VGA driver.

Try to run tests/vesainfo utility in DOS and see if 16-bpp modes are
supported by hardware and VESA BIOS.  If it says that 16-bpp modes are
supported, then try tests/test in DOS, selecting VESA or VBE driver.

It is possible that SVGAlib driver autodetection is disabled.  Then
you should select SVGA driver in allegro.cfg with 'gfx_card' option.
