Post Radeon resolution & dual-screen?

I've got a special behaviour on my ThinkPad.

I installed OpenBSD 5.7, and after a few fights, it works fine now.
The Radeon works fine, with 1920x1200 resolution.

I installed a dual-screen, with the VGA link and my HDTV (1920x1080).
Dual-screen works, the TV copies the laptop screen.
I just have to adjust the definition, downgrading to 1920x1080 to have the same pictures.

But the problem is before X is launched, with the console.
When I use the laptop alone, dmesg indicates :
# dmesg
radeondrm0: 1920x1200
When plugging the TV and using dual-screen :
# dmesg
radeondrm0: 1024x768
The problem is that the console output fits 1024x768 on a 1920x1200 screen...
So I've a small console on a wide screen.
The console is something like a quarter or a third of the screen...

X still works fine, with a normal 1920x1200 (or anything else).

So, does anybody ever heard about that, and if so, is it possible to fix ?
Or is it a normal behaviour ?

And is it possible to have two different display on the dual-screen ?
I currently use XFCE (but I don't really care about the DE. One or another...).

Edit : It only occurs when the TV is OFF, still plugged.
In case of emergency

Separated from the laptop compatibility parent thread. Other dmesg(8) listings from this same laptop can still be found in that thread.

Given that this post is asking about X(7) dual-monitor configuration, & multiple messages may be posted in response, discussion is being isolated here into is own thread.
