DD-WRT TFTP addition

I would like a custom firmware with a TFTP service built in (maybe atftp) with a small tftp load to be incorporated. Image should fit Linksys WRT-54GL (4mb) Mini load image should be able to: - dhcp - tftp (option 66) broadcast TFTP in dhcp - tftp deamon / server with support of 900kb folder containing MGCP firmware files for cisco ip phones. - ability to SSH or terminal into router remotely - ability to run 'terminal' within the router to access subdevices in the network
