Has anyone been able to use a LCD display compatible with the HD44780 on the beagle board? Any hints, suggestions or directions?

Hi Nuno,

Please consider LCDproc project:

I think schematics with PCF8574P port expander on I2C bus fits BB very
well:

If you want to drive it with i2c newhaven display has some nice options. if you are looking to drive a byte or nibble wide device, you’ll have to look at how to get a byte or nibble out of the beagle.
