Since the beginning of July 2010 MeshCube support works again in OpenWrt trunk and Backfire branch. 
how to flash
to install openwrt is basically the same as installing nylon images, so see: MeshCube/InstallFilesystemImages for more details. here's a short recap just for OpenWrt:
from yamon via TFTP
connect a serial cable (MeshCube/SerialPort) and during startup press Ctrl-C to enter the YAMON bootloader. set up a TFTP server before.
erase 0xbfd00000 0xf0000 erase -s load /openwrt-au1000-vmlinux-flash.srec load /openwrt-au1000-jffs2-128k.srec
from within nylon
you can also flash from within a running nylon system. when writing the filesystem image, however, you have to be careful to kill all processes which could want to read or write the filesystem while flashing - because you are basically replacing the filesystem from under your feet. here is an example session:
get the files, eg.:

kill all processes (don't kill sshd if you are connected via ssh):
