Hello,

I would like to add my 2c.

The list of cards with unprogrammed regdomain can be extended with
several relatively modern models:
  * MikroTik R11e-5HacD (QCA9882 based)
  * MikroTik R11e-5HacT (QCA9880 based)
  * QNAP QWA-AC2600 (QCA9984 based) [1]

As you can see these are powerful and massive cards for WISPs. Or at
least to run as an AP. I also know a bunch of .11a/b/g/n cards with
zero regdomain and the same target audience. Except maybe for the
legacy Wistorn CM9, which is a relatively compact card.

Also, a huge number of wireless routers and access points have
unprogrammed regdomain. But probably this is not the case, since they
anyway can not run a stock kernel.
