I didn't tryed sd_loader until now, but as i read, i should be able to do this while in Recovery menu.
I will try also to modify the u-boot to load fastboot, as eureka suggested, as soon as i get home.
I'm not familiar with the mfg* stuff (I try to avoid Windows as much as I can), so I don't know what the command-line tools you mentioned mean.
Essentially, mfgtool comes with a GUI to load and start stuff on a Kindle which is in USB downloader mode, and it includes 3 custom u-boot images (fastboot, diags, main). imx_usb_loader does the same, but through a command line. I obviously prefer the latter, because it "just works" on Linux, no need for Windows, no need for Windows driver hell.
But if I'm correct, and your device works in USB downloader mode, both should do the job of getting your device into fastboot mode, from where you can follow the "normal" debricking procedure. So use whichever OS/tool you prefer
