Ive come across MIPS hardware wherein a seperate i2c bus provides 
connectivity to temepeture sensors and fans.
In that case, i2c devices can interrupt every other activity. I hope your 
framework supports that type of hw too.

It should be no problem ... that would be entirely hidden from the 
middle-layer by the I2C interface driver (the back-end).

...though, I must admit, I'm a little confused as to why you wouldn't 
use the SMBus controller that comes on ~every PC motherboard these 
days, but whatever :-)
