However, I've been stuck at getting the USB recognized during early boot, as the stick simply doesn't register if it has a GPT during the kernel's processes. I don't know if it's an issue with my kernel config, or with the standards used to boot from USB, or something else I've never used before. This is quite literally one of two hurdles left before I can make a proper release (the other being an ISO image). Where do I start looking for the problem?

Does the bios/uefi firmaware/whichever you name it recognize the stick?
If it does, one option is as follows:
Can you successfuly boot another image, such as other people/distors/whatever,
as long as you can reasonbly assume many people on the internet successfuly 
booted that image? Or, hopefully, that image has a forum/mailing list /whatever
to discuss booting it?
Hopefully, after being able to boot another image, you will be able to compare 
that image to yours. Or better, compare the way that image is produced to
how you are making yours.
