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.
