Nios II Linux v1.4 released

Hi, I am new to Nios II development. I saw that Quartus II v. 8.0 does include an MMU, so that an actual Linux can in principle be run. Does anyone have a suitable Linux boot disk image or ZIP file that could be loaded onto, say, an SD card, so it could be used with a suitable development board (such as the Terasic DE3 board) to allow a Nios II design on the board to boot up into Linux straight off of the SD card's filesystem? Or barring this, can you point me at the next best thing to get into a "real" seeming Linux environment on the Nios II? The DE3 also has 1GB DDR2 RAM. Thanks very much.
