Playing with device trees under qemu?

[Rob Landley]

Google is being unhelpful here.  If I want to:

A) play around with the recent device tree support patches for the kernel

B) boot them under QEMU

Where do I go?  The closest thing to a device trees website google 
finds is http://elinux.org/Device_Trees which doesn't mention qemu at 
all.  There was a CELF proposal last year to add device tree support to 
qemu, which is inexplicably attributed to me:

http://elinux.org/CELF_Project_Proposal/Add_Device_Tree_emulation_support_to_QEMU

And google also found http://www.linux-kvm.org/wiki/images/f/fe/2010-forum-armbru-qdev.pdf
and a kvm (not qemu) status page http://www.linux-kvm.org/page/Qdev_status
but none of them are the "go here, download this, do that" variety...

Any suggestions, or is it not ripe enough to play with yet?
