ok, I think I forgot to mention that I want to avoid rebooting.
I'd simply like to have the possibility to set the correct video mode
when I activate that particular port on the KVM.

The system receives a bunch of video parameters upon boot, but if that
port on the KVM is not the active one it is 1024x768 and not the real
setting that the monitor reports to the KVM switch.
I'd later like to force that exact video mode.
The kernel does it somehow and if possible I want to have that
functionality on manual request.
