Poor design. The driver knows the 5-bit address and the 6-bit key data
and translates this into a key code event using a static table with 256
entries. (RCMM has 8 bit data)
Everything, down to the /proc/av7110_ir format, uses this 256 entry
table format, and there is no way to specify two tables for two devices.
If you want to take a look, this is in
drivers\media\dvb\ttpci\av7110_ir.c. The code is easy to understand.
Older drivers may have this file in a different location.

This seems to have changed several times on different driver versions,
and documentation is minimal anyway.
