Out of the ether, Chris D. Faulhaber spewed forth the following bitstream:

Even with:
device smbus # Bus support, required for smb below.
device intpm
device alpm
device smb
device iicbus # Bus support, required for ic/iic/iicsmb =
below.
device iicbb
device ic
device iic
device iicsmb # smb over i2c bridge
And finding:
iicbb0: <I2C generic bit-banging driver> on bti2c0
iicbus0: <Philips I2C bus> on iicbb0 master-only
iicsmb0: <I2C to SMB bridge> on iicbus0
smbus0: <System Management Bus> on iicsmb0
smb0: <SMBus general purpose I/O> on smbus0
iic0: <I2C general purpose I/O> on iicbus0
smbus1: <System Management Bus> on bti2c0
smb1: <SMBus general purpose I/O> on smbus1
It still panics:
