xbd0: WARNING: cache flush not supported by backend

Hi,

network worked (once) with patched domU installer
(http://blog.yellowback.net/uploads/netbsd-5.99.27-xenfront-rx-copy.patch)
but there seem to be another little issue with -current domU.  After the
netbsd partitions get formatted I get,

     Status: Finished
    Command: /sbin/mount -tffs -o log /dev/xbd0a /targetroot/
     Hit enter to continue

The domU config,

name = "bsd"
memory = "512"
kernel="/root/tp/compile/obj/releasedir/amd64/binary/kernel/netbsd-INSTALL_XEN3_DOMU.gz"
disk = [ 'file:/data/bsd/bsd.disk,xvda,w' ]
vif = [ 'ip=192.168.0.12, vifname=veth2' ]
vcpus = "1"
