<pre>Just to check: When you boot with nomodeset, does any screen work?
According to the reg dump HDMI is enabled, VGA is disabled, but the pll is
complete bs.
Also, does the BIOS manage to light anything up properly? At what point do you
start to see the black screen (linux or boot-loader/grub or ...)?
Can you try to remove any special options from grub like gfxmode or similar and
let grub run in legacy vga mode?</pre>
