Yes, if you've booted entirely off the SD card then changes to internal
flash wouldn't hose your running environment. I've been imagining a flash
util plus kernel in a uImage on SD, net result that you stuff the flash
util uImage and the rootfs, kernel uImage or whatever on the SD with it,
boot the FR from SD and it pops up the flash menu.
