Problem with LCD when porting linux 2.6.28.rc4 on MV6410 (ARM-S3c6410)


I am porting linux version 2.6.28.rc4 on my board (mv6410-lcd: arm s3c6410 ).
I check out source code from http://git.kernel.org/?p=linux/kerne....git;a=summary.
this kernel has a driver for s3c framebuffer and s3c_lte480wv . But my lcd still not display.
Here is the message on dmesg:
...
S3C6410: Initialising architecture
S3C DMA-pl080 Controller Driver, (c) 2006-2007 Samsung Electronics
Total 32 DMA channels will be initialized.
io scheduler noop registered
io scheduler anticipatory registered
io scheduler deadline registered
io scheduler cfq registered (default)
S3C_LCD clock got enabled :: 133.000 Mhz
LCD TYPE :: LTE480WV will be initialized

Console: switching to colour frame buffer device 100x30
fb0: s3cfb frame buffer device
Serial: 8250/16550 driver4 ports, IRQ sharing disabled
s3c6400-uart.0: s3c2410_serial0 at MMIO 0x7f005000 (irq = 16) is a S3C6400/10
s3c6400-uart.1: s3c2410_serial1 at MMIO 0x7f005400 (irq = 20) is a S3C6400/10
......
The message seems say that: framebuffer driver has ok but my lcd still doesnot display,

Can you tell me what configs or file I have to change or what steps I have to follow to solve the problem (I have a kernel version 2.6.21.5 from the CD when I bought the board, it certainly run on this board).
Please help me to solve this problem.
