That kernel has a framebuffer driver and fbcon support in there.
Unfortunaly that conflicts with the uml console driver, so that one
isn't there.  The xen guys have the same problem, so hopefully we'll
have the linux vt subsytem switchable at runtime soon (i.e. we can
enable it only when using the framebuffer console and otherwise use
the uml console driver), but that doesn't work yet.

At the moment the default console of that kernel is /dev/tty0,
i.e. the linux vt subsystem.  To see any messages you have to either
enable the framebuffer (and thus fbcon) or reconfigure the console
device.  Here are some examples:

virtual serial console on the current terminal:
  $ linux console=ttyS0 ssl0=fd:0,fd:1

enable framebuffer & fbcon:
  $ linux x11=800x600

use fbcon, additionally print the kernel msgs to stderr:
  $ linux stderr=1 console=stderr console=tty0 x11=800x600

just the kernel messages on stderr:
  $ linux stderr=1

HTH,
