That's true.  However, the number of custom ARM-based devices with
no changes to the bootloader (which is probably U-boot) is likely zero.
I suspect there may be kernel changes too.

Yup.  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.
