Since 2.6.38-rc2, there is no more lirc_i2c module. Upon googling around, I found this thread (http://www.gossamer-threads.com/lists/mythtv/users/470613?do=post_view_threaded#470613) which teaches how the ir-kbd-i2c module can be used here.

A big part of the problem here is the in-kernel compatibility breakage
that was introduced in 2.6.36. Tools that worked before (lsinput, inputkbd)
no longer work with 2.6.36 and beyond, and patched versions of those usually
won't work with 2.6.35 and earlier. A real ugly mess that somebody snuck in.
I've hacked my input-utils to work with both old and new kernels,
and have my PVR-250 remote working again here now.
Getting it working really well though, requires disabling
the b0rked IR repeat logic in (kernel) ir-keyboard.c
and replacing it with something saner that doesn't fight
the input layer's repeat logic at the same time. :)
