I have a LCD(LQ035q7db02). It supports 240X320(H X W). I have a frame
buffer driver for it and it works well. But I have to change the display
mode in 320X240 (H X W) . I don't know whether I can change the frame
buffer driver to implement it. If can, how to change the driver. If anyone
can help me? Thanks!

You need to support 2 methods:
xxxfb_check_var()
- check the passed var structure for compatibility with the hardware. If
not, it's acceptable to return a modified var that is agreeable to the
driver.
xxxfb_set_par()
- change the hardware state according to the contents of info->var.
Once you've added the above methods, you can choose the driver's initial
mode by various methods, or you can use fbset to change the resolution after
the driver loads.
