[Buildroot] BR 2012.rc1 :: DVI not activated on pandaboard?

[MERCADIER Johann]

Hi all,
  Now that I try to switch to a graphical output. As the uImage generated
by BR still does work I compile one manually (3.2.7), it works great till
It's used on console mode then I add all options needed to get DVI
activated as explained on the following website:
http://omappedia.org/wiki/Bootargs_for_enabling_display
http://omappedia.org/wiki/DSS_CONFIG_options

modify the boot script in the following way:
___[ BOOT.SCRIPT
]________________________________________________________________________________________
mmc rescan
fatload mmc 0:1 0x80000000 uImage
setenv bootargs vram=32M console=ttyO2,115200n8
mem=456M at 0x80000000mem=512M at 0xA0000000 omapdss.def_disp=dvi
omapfb.mode=dvi:1280x1024MR-24 at 60smsc95xx.macaddr=76:2F:97:85:4F:56
root=/dev/nfs rw
nfsroot=192.168.1.44:/home/johann/rootfs_TEST,nolock,wsize=1024,rsize=1024
ip=192.168.1.235 rootdelay=4 init=/linuxrc
bootm 0x80000000

when booting I get there, the pandaboard probably still continue the boot
process but nothing is displayed on the monitor?...

If someone can understand why nothing is displayed on monitor, please tell
me or us (probably not the only stuck with it!)

thanks
