What changeset are you using?

Note that I got this by just doing 'hg clone
http://xenbits.xensource.com/xen-unstable.hg'
I did not change a thing, just did a make world and installed the stuff.
(Am I wrong to assume that this procedure will produce a xen that works?)
Did your kernel config work before?
I had no special config, just was using whatever the default is in the
repository I cloned.
My Xen domO

Might also help to try a loop image as well and see if that will play
nice.
That's what I'm doing. My config file looks like this:
...snip...
xm_vars.check()
kernel = "/boot/vmlinuz-2.6.12-xenU"
memory = 128
name = "Rob-VM%d" % vmid
cpu = vmid # set based on vmid (mod number of CPUs)
nics=1
disk = [ 'file:/xen/disk-images/dom1.fs,sda1,w']
ip = add_offset_to_ip(get_current_ipaddr(),vmid)
netmask = get_current_ipmask()
gateway = get_current_ipgw()
hostname= "vm%d" % vmid
root = "/dev/sda1 ro"
extra = "4 VMID=%d" % vmid
Here's another bit of info... running 'xm block-list' on the domU that
doesn't boot successfully gives:
(2065 ((virtual-device 2065) (backend-id 0) (backend
/local/domain/0/backend/vbd/1/2065) (ring-ref 8) (event-channel 6)
(error '2 reading backend fields at /local/domain/0/backend/vbd/1/2065')))
