This topic was brought up before for the 2.6.38 kernel one month ago
http://lists.xensource.com/archives/html/xen-devel/2011-04/msg01345.html
It wasnt mentioned there that upstream has some missing functionality for the
console, so i assume that it should work.
First my config: xen 4.1, 2.6.39 upstream linux-kernel, both 32-bit
As soon the dom0-kernel is booting all output is cleared and the screen stays
black, but the kernel is booting fine and i can login and start programs etc.
When i start X the output on the screen works normally. As soon i finish X,
the screen turns black again.
I added the following patch to the 2.6.39-er kernel, and the output on the
console works fine for me on 32 and 64 bit dom0 kernel (the following patches
are from Jeremys xen repository).

xen: allow enable use of VGA console on dom0
There was another patch to make the vga-console work with 32-bit-kernel. But
for me it worked without it.

xen/i386: make sure initial VGA/ISA mappings are not overridden

Nice!

When you switch consoles do you go to text mode?

Yes, simple 80x25 text-mode.

This topic was brought up before for the 2.6.38 kernel one month ago
http://lists.xensource.com/archives/html/xen-devel/2011-04/msg01345.html
In this thread it wasn't mentioned that upstream has some missing
functionality for vga-console support (as far i have seen), so i assume that
it should work.
First my config: xen 4.1, 2.6.39 upstream linux-kernel, both 32-bit
As soon the dom0-kernel is booting all output is cleared and the screen stays
black, but the kernel is booting fine and i can login and start programs etc.
When i start X in the dom0 the output on the screen appears normally. As soon
i finish X, the screen turns black again.
I added the following patch to the 2.6.39-er kernel, and the output on the
console works fine for me on 32 and 64 bit dom0 kernel (the following patches
are from Jeremys xen repository).

It certainly seems likely that this would be required, thanks for
tracking it down.
Konrad, will you pick this one up?

Konrad has been reworking the handling of _PAGE_IO recently, it's quite
possible this one is no longer relevant.
