Most radio modules would have an embedded firmware that in addition to the radio handling, should enforce regulatory constraints (i.e preventing the use of 5GHz DFS channels if radar use is detected).
Building these firmware images is something you are (usually) only equipped to do under NDAs from the silicon manufacturer (or only done by request from the manufacturer).
My understanding (and what I have gathered from previous threads on the subject) is the FCC is going after the embedded radio firmwares, and mistakenly (or due to extreme lack of knowledge) named OpenWRT,DD-WRT as offenders.
Otherwise, the effect of this would be to outlaw PCIe and USB WiFi, Bluetooth etc. cards/adaptors unless sold inside a computer with a locked bootloader.
- jdiez17 11y agoIt would only take a motherboard with a PCIe slot and an unlocked bootloader to circumvent that strategy. You would use it to flash the firmware in whatever device you want to unlock and then use it on the computer with the locked bootloader.

Lenovo already does this for laptops, you have to use a Whitelist Wifi card, they claim it is to comply with existing regulations from the FCC, which this will expand.
