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).
commit 09e5e7caf4eac83c010ec3d209cc3dfbe1444ae0
Date: Mon Feb 9 12:05:54 2009 -0800
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
Or ss the console suppossed to work without this patches?

When you switch consoles do you go to text mode?

Yes, simple 80x25 text-mode.

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.
