No, it covers only the one I can personally test and confirm to require
this quirk, beyond my own ASRock Q1900DC-ITX[1], there are at least:
Celeron J1800:
- ASRock D1800B-ITX, http://www.asrock.com/mb/Intel/D1800B-ITX/
- ASRock D1800M, http://www.asrock.com/mb/Intel/D1800M/
Celeron J1900:
- ASRock Q1900B-ITX, http://www.asrock.com/mb/Intel/Q1900B-ITX/
- ASRock Q1900-ITX, http://www.asrock.com/mb/Intel/Q1900-ITX/
- ASRock Q1900TM-ITX, http://www.asrock.com/mb/Intel/Q1900TM-ITX/
- ASRock Q1900M Pro3, http://www.asrock.com/mb/Intel/Q1900M%20Pro3/
- ASRock Q1900M, http://www.asrock.com/mb/Intel/Q1900M/
Pentium J2900:
- ASRock Q2900M, http://www.asrock.com/mb/Intel/Q2900M/
- ASRock Q2900-ITX, http://www.asrock.com/mb/Intel/Q2900-ITX/
All very similar boards, but their BIOS state might differ.
However I've never had access to any of those and could only do an
educated guess about their DMI identification[2]. While researching my
problem on the web, it seems that Baytrail-D boards from several vendors
might be affected (e.g. Gigabyte). Sometimes apparently fixed by later
BIOS updates, but I can only confirm the problem and workaround for my
own ASRock Q1900DC-ITX mainboard (where all published BIOS versions are
affected).

[2] I know that the very similar ASRock Q1900-ITX board uses
DMI_MATCH(DMI_BOARD_VENDOR, "ASRock"),
DMI_MATCH(DMI_BOARD_NAME, "Q1900-ITX"),
but I don't have direct access to that board and can't
check if it is also affected by this problem.
