The User Settings Bus, as it exists in N210 actually dedicates an entire (empty) settings bus with 8bit address space (32bit aligned) for custom registers. This way it was thought less likely that issues such as you have indicated with address space collisions would occur. Its mapped from address 0x0 in its own private address space.

Both the tutorial (http://lists.ettus.com/pipermail/usrp-users_lists.ettus.com/2013-April/006558.html) and the examples included with the FPGA code (uhd-maint for N210) say to use a BASE address of 0. Won't this overwrite register 0 of SR_MISC defined in the u2plus_core.v file?
