It depends on hardware.

HDMI over ATI graphic board should work with fglrx driver.  IIRC, HDMI
on radeonhd came after 11.1 release.  On Factory, it should work.

HDMI over Intel graphic isn't supported on 11.1.  On Factory, it could
be, but not sure.  The XOrg:Devel repo should work, though.

In general, X has to run to enable HDMI output, because the HDMI is a
composed output of both graphic and audio, and the graphic driver has
to cooperate with the audio part in some role.

Also, note that the way to choose HDMI output depends on the hardware
implementation.  In some cases, you'll have an individual HDMI output
audio device, and in some cases, HDMI is bundled together with the
normal analog output.  That is, the hardware implementation of HDMI is
very chaotic right now...
