At the time dual-head features were added, there was no OEM VE card available. The dual-head support in x420 radeon driver hasn't been tested on any OEM card. It turns out DELL has some cards with OEM version of BIOS not working with current driver on their 2nd head. AFAIK, DELL has cards with two DVI-D outputs and with two VGA outputs (all from a dangle). It appears if the 2nd head is connected to a CRT, some register bit (CRT2_ON?) has not been set correctly and you'll get a blank screen. If the 2nd head is connected to a DFP, it's totally not handled. I'm not sure when someone (or myself) can have time to have this support added. Not sure what kind of card you have, maybe you can help to debug it :-)
