You are right about what the suspect devices are, having IOAPICs
unrecognized seems like it could be a problem.

When you say others are using such systems, do you mean they are
using them with FreeBSD RELEASE?

If you want info on the missing ID's try pciids.sourceforge.net, however
figuring out what to do may require some work. In the easy cases you
find a driver that is good enough but just doesnt have these new ID's
in it, and a simple entry or two in a array will get you going. Course
there is also going to be the case where its not that easy...

Fraid I can't be too much help beyond that, hope it gets you headed
in a direction you need anyway.

Good luck,

Jack
