It won't support all of them (I'm not sure that any board supports all of
them).  But it will support some of the high resolution (>= 800 x 600)
256 color modes.

Double buffering functions in not planned at this time.

Several Super VGA boards are currently supported including: 

Orchid Pro Designer With multi-freq monitor, 800x600x16 colors (mode 0x29).
Paradise VGA Plus   With multi-freq monitor, 800x600x16 colors (mode 0x58).
Trident 8900        With multi-freq monitor, 800x600x16 colors (mode 0x5B).
Video 7 VEGA VGA    With multi-freq monitor, 800x600x16 colors (mode 0x62).
Diamond Flower Inst With multi-freq monitor, 800x600x16 colors (mode 0x64).
VESA (multi vendor) With multi-freq monitor, 800x600x16 colors (mode 0x6A).
Everex EVGA         With multi-freq monitor, 800x600x16 colors (mode 0x70).

There are about 4 functions that you have to write in order to make a 
crude (slow) driver with FG.  fg_init_YOUR_BOARD(), fg_term_YOUR_BOARD(),
fg_YOUR_BOARD_drawdot(), and fg_YOUR_BOARD_readdot().  If in addition you
write a fast fg_YOUR_BOARD_drawline() for the case of horizontal lines then
you will make a significant speed up for the library as a whole.

I'm not sure of the details.  Send email to zortech-ed@zortech.com.  I think
it is available elsewhere.
