Dtrace required modules?

[HeTak]

Hi there,

I'm new in using Dtrace. I need to re-compile my kernel a lot so i'm using
MODULES_OVERRIDE option of /etc/make.conf to make my kernel compile faster.

Would you please tell me what are the exact kernel modules of which dtrace
needs to be recompiled with kernel?
or how I can get the list?

Thanks in advance :)
