With 5.10.12-rt26 the controller still does not initialize at all
though (/dev/fw0 does not appear):

So it is either config or chipset specific. Did you posted a link to
your .config?

The current config can be found on the AUR [1].

The equivalent mainline kernel config (note, that it states it is for
5.10.13, but is actually used for 5.10.14 as well) where initialization
of the controller works (but the initialization of a connected device
does not, when using threadirqs) is here [2].
