I would like to get an X server running on a
640x480 Sharp TFT color panel connected to
an ISA single board computer.  Advice on how
to do this will be much appreciated.  Here are
some details on the setup.

FreeBSD 3.x
Axiom SBC8242
      486
      Chips and Technology F65550 video controller.
Sharp LQ64D343 640x480 18bit color TFT display.

The SBC8242 has jumper settings to support TFT Color panels.
    #5, 640x480 Sharp TFT Color Panel
    $6, 640x480 18-bit TFT Color Panel

The SBC8242 User's Manual lists VESA VBE modes that are identical to
the CRT/TFT modes listed in a Chips and Technology application note.

VESA VBE mode 0x112, grapnic mode, Pack pixel memory organization
Res               Screen refresh       horiz. freq.       dot clock

640x480x24bpp         85 Hz              43.3 KHz         36MHz MHz      900KB
