However, the number of custom ARM-based devices with no changes to the bootloader (which is probably U-boot) is likely zero.

The Linux kernel allows proprietary modules as an exception to the GPL, as long as they don't link to EXPORT_GPL_ONLY symbols. However, if you sell a device with GPL'd software on it, you are required to provide sources to any GPL'd software present on the device. Regards, Dianne.
