Same here. I have an xps 13 running ubuntu 14.10. When I upgraded from
12.04 (as installed by dell) into 14.04, I had to blacklist i2c_hid.
After upgrading to 14.10, i needed to remove the blacklisting, as others
reported. Here is the interesting thing:  I needed to blacklist two
different i2c modules (but see my first note below).

####
me@myxps:~$ grep i2c /etc/modprobe.d/blacklist.conf 
# blacklist i2c_hid
# blacklist i2c_i801
####

A few notes:

* when dealing kernel settings in laptops, I find that it's often the
case that it's better to shut down and power cycle, instead of
restarting. It seems like the BIOS doesn't quite get the hardware reset
on a restart.

* Joseph: when testing upstream, what's the expected/desired behavior?
It seems like 14.10 is already working ok for most users. It seems to me
that the blacklisting was a workaround in 14.04, not needed anymore. Or
are you asking those who still have issues after de-blacklisting i2c_hic
? To those folks, I suggest trying a full shutdown and remove the power
chord, and perhaps also removing the blacklist for  i2c_i801 and see if
that helps.
