Does the DVI port work in text mode or when the bios is active during boot? 
Your setup uses an external TMDS chip, however no external tmds init table is
available in the bios.  If the bios does not init the TMDS chip and there's not
TMDS init table, the driver does not know how to power up the external TMDS
chip which drives the DVI port.  fglrx apparently does.
