That is an excellent point. I knew this information and I have suggested it as options for some users, but I did not realize until you pointed it out that this is a simple way prevent the kindle from dropping out of fastboot mode when changing host PCs. It makes perfect sense. Just do "fastboot setvar bootmode diags" from fastboot, then from diags used the fastboot exit option to SAVE fastboot mode so it will work with any fastboot.
That should be added to the first post of the "simple debricking" thread.
