I also had to modify the bootscript in the Grahame Bowland description slightly in order to get the display:
root@linaro:~# cat /boot/boot.script
setenv bootcmd 'fatload mmc 0:2 0x70000000 uImage; fatload mmc 0:2 0x72000000 uInitrd; bootm 0x70000000 0x72000000'
setenv bootargs 'console=tty0 console=ttymxc0,115200n8 video=mxcdi1fb:GBR24,XGA di1_primary tve root=/dev/mmcblk0p3 rootwait ro'
boot
root@linaro:~#
Thank you Grahame!
