The lm-sensors mailing list would be the best place to ask, but this will do.
I am copying the list.

The driver supports BMR45x, which are the same type of controller. So, yes, the driver
should work. Just give it a try. If the generic driver doesn't work, you (or I)
can write a little front-end driver to tell the PMBus core driver which registers are 
supported. Worst case the driver may need some patches, but that is unlikely.

Do you have a datasheet ?

Thanks,
Guenter
