After kernel booted up NO DISPLAY ON MY DEVKIT-8000, 4.3" LCD #143

Hi !
  I am new to Devkit8000. I  ported 2.6.29 Linux Kernel on the Devkit8000 board.The board booted up and given command line prompt on minicom terminal but I am not getting Display on LCD(4.3").
In this case I was taken 2GB MMC/SD card and partitioned the SD card,first one 
as FAT and second on is EXT3 (as specified).
I down loaded the source from ""http://code.google.com/p/0xdroid/wiki/Source"
and followed the procedure as given.That successfully compiled/build. 
Note: If I flash images to NAND flash,by using installer 
(uImage.bin,0xkernel.bin,flash-uboot.bin,android.ubi) it is displaying on the 
LCD . But I want to boot from dual partitioned SD/MMC 
card.(MLO,uImage,u-boot.bin in FAT partition and Angstrom File system in EXt-3 
partition).

boot args I set: 
setenv bootargs 'console=ttyS2,115200n8 root=/dev/mmcblk0p2 rootfstype=ext3 rw 
rootwait noinitrd rootdelay=1 video=omapfb:mode:4.3inch_LCD'

I tried for kernel source(2.6.28), which is given in Devkit-8000 CD.In this 
case also same problem.

If anybody knows please help me.

Thanks in Advance...

First this is not support forum so please don't ask question here. You can post 
general questions to 0xlab-discuss[1] or development questions to 
0xlab-devel[2].

For 0xkernel the correct video parameter is "omapdss.def_disp=lcd 
omapfb.mode=lcd:480x272"
