1/ oemake unslung-image
2/ slugtool unpack the resulting image
3/ put the ramdisk.gz in your tftpboot area
4/ reboot the slug and interrupt redboot
5/ type "move" to move the unslung-1.11-beta kernel from flash to ram (assuming you're unslung - otherwise, just put the unslung-1.11-beta kernel in tftpboot too)
6/ load ramdisk.gz as normal from tftp
7/ if you did get the unslung kernel from flash with "move", then load it tftp now
8/ exec 0x01d00000
[make sure you don't have a disk attached]
