If you give Matthieu's link[1] a quick read, the OpenBSD developer that
reverse engineered the regulatory blob seems to indicate that the FCC

I'm not sure to what extent this is accurate, but it would seem that you would
leave the driver functionally impaired if you simply removed the regulatory
checks.
