PC87431 is not - need full datasheet.

ipmi_smb doesn't exist in the mainstream kernel yet.  I'm working on 
getting it in; the driver and some rather large related changes to the 
I2C layer were posted on lkml (and the sensors list, too) a few days 
ago.  Those were against linux-2.6.11-rc2, not against 2.6.7, and those 
patches will almost certainly not apply against 2.6.7.

If you want to use the older smb driver, it does work, but certain 
functionality won't work, primarily things that occur at panic time like 
storing panic information in the SEL and extending the watchdog.  It's 
available at http://openipmi.sf.net.  There is a 2.6.7 version that will 
probably work, though it doesn't do automatic DMI detection so you will 
have to hand-specify the parameters.
