smbus and freebsd 5.3

[Andrea Riela]

Hi folks,

I've a mobo GA-7VT880 (Gigabyte with VIA KT880 chipset), and for 
monitoring the temperatures I've to use healthd or lmmon with SMB 
interface.

Well, the man healthd and man lmmon say that I've to add in my kernel:

controller       smbus0
controller       iicbus0
controller       iicbb0
controller       intpm0
device           smb0 at smbus?

but this is for 4.x, and not for 5.3, I think.
Well, I've tryed unlucky with:

# System Management Bus
device          smbus
device          smb
device          iicsmb
device          bktr
device          iicbus
device          iicbb
device          iic
device          ic
device          ichsmb
device          intpm

I don't see a /dev/smb, and if I try with healthd + smb interface the 
output is obviously:

healthd -d -S
/dev/smb0: No such file or directory
InitMBInfo: No such file or directory

There's someone using SMBus that could help me?
Any advice will be appreciated.
Regards
Andrea
