You are correct. I happen to have one of those ancient remote
controls myself and it does use device address 0.

Please refer to http://www.sbprojects.com/knowledge/ir/rc5.htm
for an overview of device addresses.

It's something I forget to deal with in that patch. A solution
would be to allow a device address to be a module param to
override the more modern addresses of 0x1e and 0x1f.

I can't remember addresses off the top of my head but I believe
the modern silver remotes use 0x1f and the older black ones
use 0x1e. I think the black one I have came with a now dead
DEC2000.

The problem with reverting the patch is that it makes modern
systems unusable as HTPCs when the television uses RC5. This
is a more important IMHO than supporting what in reality is
an obsolete remote control.

cya!
