thanks for the reply, Will try that later today However FYI ... If I choose
anything else other than omapfb.mode=tv ( For eg dvi or lcd ), /dev/fb0 ,
/dev/fb1 will come back, They disappear only when I use omapfb.mode=tv, Not
sure it really matters but thought should let you know.
Miles to go before I sleep...
