VRAM Setting For Angstrom

Hi All,

For increasing the VRAM in Angstrom I tried multiple bootargs like
setenv bootargs ‘console=ttyS2,115200n8 console=tty0 root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait omapfb.mode=dvi:1024x600MR-16@60 vram=32M omapfb.vram=1:8M,2:8M’

setenv bootargs ‘console=ttyS2,115200n8 console=tty0 root=/dev/mmcblk0p2 rootwait rootfstype=ext3 rw omapfb.vram=0:8M omapfb.mode=dvi:640x480MR-16@60’

But the VRAM is remain as default (1.4MB)

So can you suggest me the Proper Bootarg.
I tried with adding omapfb.debug=yes
And the output of dmesg is

Have a look at the scripts at http://cgit.openembedded.org/cgit.cgi/openembedded/tree/recipes/angstrom/angstrom-uboot-scripts

Thanks Koen.
As per the uboot script I have tried

setenv bootargs 'console=tty1 omapfb.mode=dvi:1024x600MR-24@60
root=/dev/mmcblk0p2 rootwait rootfstype=ext3 mem=99M@0x80000000
mem=128M@0x88000000 vram=32M omapfb.vram=0:M,1'

But still there is no change in the vrarm value.
Is any other way to set this VRAM.

omapfb.vram=0:M,1 is not a valid vram setting

Thanks Koen.

omapfb.vram=0:M,1 is not a valid vram setting

Can you pls tell me the right one.

Have a look at the scripts in the link I posted earlier, those show it quite clearly.
