similar dmassage tool for freebsd?

[Didier Wiroth]

Hi,
For openbsd there is a tool called dmassage . From the original doc:
dmassage parses the dmesg of your OpenBSD system, and can do three things with that information:
a) make the kernel boot faster
b)  reduce kernel size
c)  show all devices in a tree-like hierarchy 

Does a similar tool exist for freebsd which can do point b) and c)

thx
