Yes, it should be able to be remapped like any other IR code. If you're not sure of the code, here's what my empeg_ircodes file looks like:

# Do not remove this line. It is needed by the kernel. Syntax: <old>:<new>
0x0000B94613:0x0000B9461F

I haven't tested it in 2.0b3, because I haven't applied the Mk1 2.0b3 Irhack kernel image.
Keep in mind I have the SRC button on the Kenwood Steering Wheel remote mapped to the INFO button. Change the right side of the : to your preference.

Edit: Has anyone built the old hacks into the new Mk1 kernel?
