this took me a while as well, I am not 100% sure if it is the nosmp in the 
boot opts or if it was the cpu= and vcpu= that made it work.

#kernel = "/xen/kernels/NetBSD/netbsd-INSTALL_XEN3_DOMU"
kernel = "/xen/kernels/NetBSD/netbsd-XEN3_DOMU"
# Initial memory allocation (in megabytes) for the new domain.
memory = 256
name = "netbsd.xen.prgmr.com"
cpus = "1"
vcpus = 1
vif = [ 'bridge=xenbr0' ]
disk = [ 'phy:/dev/folsom-xen/netbsd.xen.prgmr.com,0x03,w' ]
root = "/dev/wd0d ro nosmp"


note the '0x03' in the disk... you use 0x301

the kernels I built are at
http://prgmr.com/~lsc/netbsd-INSTALL_XEN3_DOMU
http://prgmr.com/~lsc/netbsd-XEN3_DOMU

it works for me.
