After the actility firmware is installed you will need to follow the mLinux instructions for flashing the firmware here: http://www.multitech.net/developer/software/mlinux/using-mlinux/flashing-mlinux-firmware-for-conduit/
You will need to extract the uImage.bin and rootfs.jffs2 files from the AEP bin. Simply treat the .bin as a tar.gz file to extract.
