Hi Matt;

I'm not particularly biased in favor of UDI. As a matter of fact I think the UDI
people always thought of it a secondary driver framework. I understand it should
basicly works on FreeBSD 4.x though, so I just wanted the idea floating around,
if it becomes important later on, great, if it definitely dies.. so be it..
I am wondering though.. will DragonFlyBSD keep newbus, perhaps as a userland API?
FreeBSD is making changes there (inheritance in kobj() ). What about busdma? I
guess you wouldn't want to break new drivers coming from FreeBSD.
	I can't really comment on Newbus, but I am sure we ought to keep
	something like busdma around, until a better API comes about.
	Not only because it's a nice interface, but it is used in NetBSD
	and FreeBSD and OpenBSD, so I guess we should stick with it.
	The KLD framework surely needs an overhaul though.  I am
	thinking about integrating changes from FreeBSD-CURRENT for
	the KLD framework, when I have some free time in my hands.
	Regards,
