People have explained these things to you.   Your processor is an LX,
and your BIOS thinks its an LX, or else Linux wouldn't boot.  vga= doesn't
work for the lxfb.  And you need to apply the timings that you were given
to make the lxfb work correctly with a TFT panel.

As for X, we cannot speculate on what your problem without the log
files.  Please send them.
