Emulated Symbios controller not configured on FreeAXP

Hi,
I found an Alpha emulator that runs on Windows called FreeAXP[1] which I=20
tried booting OpenBSD on, It's capable of booting off an OpenBSD iso but=20
as the 53c810AP (KZPAA) is not supported by siop(4), the kernel is=20
unable to configure the controller.
Is it just a case of adding the missing device IDs for the controller or=20
does siop(4) need further work to support the controller?
