AVR-Chat

Hi, I have been a member of this group for a while now, I cant remember 
if I have ever written anything before though. But hers my question:
I recently purchased a EPIA M1000 (a micro itx board with a 1 GHz 
processor) this board has some really useful interfaces but the one that 
caught my eye was the I2C/SMBUS. I googled for a while and found a guy 
that connected PIC's to the bus and let them run as slaves. But what I 
am wondering is if i can use a AVR to access internal slaves of the 
board for example the temperature sensors. I Would appreciate any links 
to information about the I2C / SMBUS and the avr.
