Linux successfully executed!

Here is the first console dump of my executing linux session (the image.dsu was borrowed from the theora project). I shall have to consider that a success. Now onto the stickier proposition of how to boot and execute from a flash card using the xilinx-xup board. I am thinking of using systemACE to package the kernel and bitfile, and then targetting a linux partition on the CF card. It all depends if system ACE can actually put things into RAM, but I believe it can look like FLASH to the FPGA so all should be alright.
