Once the "dynamic sysctls" hit the tree, I have been running a sysctl
exportation of newbus information for a few weeks (months, possibly).

There's also a "sysinfo" console program as a (badly written, since
sysctl is a pain to manipulate) reference on how to extract information
from it:

root0
nexus0
pcib0 <Intel 82443LX (440 LX) host to PCI bridge>
npx0 <math processor>
pci0 <PCI bus>
...
atapci0 <Intel PIIX4 ATA33 conroller>
ata0
ata1
eisa0: not present
vga0 <Generic ISA VGA> at port 0x3c0-0x3df iomem 0xa0000-0xbffff
sc0 <System console>
atkbdc0 <Keyboard controller (i8042)> at port 0x60,0x64
...
atpic0 <AT interrupt controller> at port 0x20-0x21,0xa0-0xa1 irq 2
sysresource4 <System Resource> at port 0x4d0-0x4d1,0x8000-0x803f,0x7000-0x700f

It just grabs the information from the sysctl export:

hw.devices.fdc0.desc: NEC 72065B or clone
hw.devices.fdc0.children: fd0,fd1
hw.devices.fdc0.state: attached
hw.devices.fdc0.irq: 6
hw.devices.fdc0.drq: 2
hw.devices.fdc0.ioport: 0x3f0-0x3f5,0x3f7

Windows-like Device Manager, anyone?
