That's no that complicated to find dependencies as it may seem.
Carefully read the kernel config file and man pages.
For example there is mainbus.
mainbus0 is installed on root, therefore the config line looks like
mainbus0 at root
Then there is bios. Where is the bios? Sure it's on the mainbus, the
config line then will look like
bios0 at mainbus0
It means that bios depends on the mainbus.
Further, there is acpi installed on bios, i.e. acpi depends on bios,
thus the config line looks like
acpi0 at bios?
All this together looks beautifully like:
mainbus0 at root
bios0 at mainbus0
acpi0 at bios?
Do you see this beautiful harmony of the UNIX music? :)
Moreover there are manual pages for all these devices:
man mainbus
man bios
man acpi
and so forth... and in the man pages you can see such recommendations
as, for example
SEE ALSO
apm(4), intro(4)
which you can admit as a cross reference (to a possible dependency).
