It is, but only for ftty{1,2}. ftty0 stays silent.

It is, ah, funny, the pc speaker got ftty0, now, for that I have a hard tim=

Hm. Is there any output I could investigate to find numbers which could poi=
nt=20
to shared resources? Like Xorg.{0,1}.log? Where to look best? Which resourc=
es=20
are there at all? What do you mean by VGA-resource? In the BIOS?

And does this mean that the single card option is not fully supported by al=
l=20
drivers? Where do/can they driver ignore it?
