Size of flashed image in fastboot mode on newer Kindles is limited by RAM size only (minus some MB for U-Boot itself and system buffers). But, for example, KT has 256MB RAM and KT's rootfs on system partition (/dev/mmcblk0p1) is about 340MB: that's why rootfs image can be flashed in fastboot mode only partially. It's understandable limitation inherited from standard fastboot.

So, to clarify things, you can't just "remove" size limitation. You'll need to implement new fastboot command for "chunked" downloading and flashing of "big" images. And change fastboot tool to support this new command.
