The people over at SDLEmu have released WIP source of version 0.2 of Handy/SDL (the SDL port of the Atari Lynx emulator: Handy). You can visit the official homepage here, or simply download it here. Handy/SDL version 0.1 has also been ported to the GP2x, calling it: HandySDL2x. This port was done by XTale, and reportedly because of speed issues, the source code was altered to render directly to the GP2x's frame buffer.
