1) Go through AVWizard blindly. The steps for me were as follows:
<Q> (for HDMI)
<0> (1080p)
<enter>
<enter>
<right arrow> (for accept resolution, continue)
<enter>
<down> (for UI2 no alpha)
<enter>
<enter>
<enter> (for analog out)
wait 3 seconds...
<right> x 16 (sound 100%)
<enter>
<enter>
2) ssh in and modify xorg.conf as follows:
Under Section "Screen"
Add
Subsection "Device"
Modes "1920x1080" #this might be different for you, but it should match the modeline name in the monitor section
EndSubSection
3) wait a few minutes until you hear the config wizard come up ("when you can see and hear me"). You're still blind at this point.
wait for HDD access to stop just to be safe.
4) reboot from ssh or power button.
voila, should bring you to the config wizard.
