Xorg and dmesg logs using HDMI and DVI

My graphics card is a Sapphire Radeon 3870 HD, with 2 DVI outputs, and I have 2
monitors; a Samsung one that has VGA, DVI and HDMI inputs, and a Philips one
that has only a VGA input.

Let my Philips monitor be connected to the first port of the card using a
DVI->VGA cable.

Now if I have the Samsung connected to the 2nd port using a DVI->DVI cable,
everything works fine, but if I connect it using a DVI->HDMI cable, at the
moment KMS initializes it displays a blank image, doesn't go into stand-by
mode, doesn't display any info, and pressing it's buttons don't do anything (no
menus).
Having it connected to the 1st port and/or just this one monitor shows same
behavior.

The Philips monitor keeps displaying the boot processs normally and it reaches
the GDM login screen just fine, so I know that xorg isn't crashing.

I collected some logs with drm.debug=15 first the Samsung connected using HDMI,
and then with it connected using the DVI port. These are attached.

I have been experiencing this bug since the early stages of KMS development, so
it's nothing new. With KMS disabled everything works fine.
