Thanks for the help Lukasz! I've made significant progress since my original posts. I found that if I CONFIG-out the usb tty stuff (since it uses the old gadget structure) I can enable the musb-new USB code and the composite gadget driver. If I also force PIO mode instead of DMA it builds. I can run "dfu mmc 0" and I get some correct behavior out of dfu-util on the host PC. But there seems to be USB transfer problems or some sort of protocol mismatch. cashwell.ubuntu:src$ sudo ./dfu-util -v -a u-boot -U ~/dfu-upload dfu-util 0.7 Copyright 2005-2008 Weston Schmidt, Harald Welte and OpenMoko Inc.

The dfu-util I'm using is from <git://gitorious.org/dfu-util/dfu-util.git>. I've also run the 0.5 dfu-util binary that comes from Ubuntu's repos. Its logging looks slightly different but also fails in basically the same way. I'm assuming that DFU has been tested in u-boot mainline. Perhaps I'm using the wrong dfu-util repo. It's so close to working it's driving me nuts.
