Strange sysctl behavior

[Paul Goyette <paul%whooppee.com@localhost>]

I just noticed that on my 6.99.2 system, sysctl is misbehaving.  Not 
only is it dumping core, but it appears to have some items not in 
alphabetical sequence (hw.dri.card0.vm comes before hw.dri.card0.clients 
for example, as well as hw.dri.card0.bufs coming after clients).

{155} sysctl hw.dri.card0
hw.dri.card0.name = radeon pci:0001:05:00.0
hw.dri.card0.vm = radeon pci:0001:05:00.0
