It looks like you are using Montavista 4.0 which explains why it's not working. You will need to either add the support expected by the davinci graphics driver to the linux fb driver, or use the included kernel source. I can't remember if it was a patch or the entire driver. You could also look at using the GIT kernel driver, which last I checked, also did not have the required support. Or you can backport the driver from Montavista 4.0.1 which is actually laid out fairly nice. In any event you will either need to add support in the driver for some of the ioctls the davinci graphics driver needs, or you will need to work-around that code in the graphics driver.
