Theoretically yes: The I2C lines from the SFP cage are connected to the 
main CPU and the Linux I2C interface is going to be accessible from 
user space. By now we have tested only reading from EEPROM in a SFP 
module but not the DDM part. I am adding this to my to-do list. Thanks 
for bringing this up! And we - or anybody interested - might port or 
create some tool for reading and interpreting DDM data. It should be 
quite simple to do.

And regarding Debian question from the another mail: Yes, I am actually 
running Debian on my prototype board. I simply created debootstrap 
image and put it to the eMMC. The only difference is a custom kernel 
with dozen patches (we are going to send them to upstream, but is might 
take some time to get them merged) and swconfig tool from OpenWRT.
