Yes, if we preserve the same logic. The above will probably still generate
ghost repeats if the user keeps the IR pressed for a long time, as we're using
a separate timer at the rc-core logic than the one used inside evdev.

That is easy. I've added a logic that detects it on Xorg evdev on some RFC patches
I've prepared in the past to allow using a keycode with more than 247 for IR's.
I'll work on a new version for it and submit again when I have some time.
Anyway, I'm enclosing a patch with the old version. 

Basically, GetRCInputs.c file adds a logic that returns a list of input devices
that are Remote Controllers, using rc-core.

This logic inside evdev gets the RC devices and adds a flag identifying them
as such:

+    /* Check if the device is a remote controller */
+    pRCDevList = GetRCInputDevices(&NumDevices);
+    for (i = 0; i < NumDevices; i++) {
+        if (!strcmp(device, pRCDevList[i].InputName)) {
+             pEvdev->flags |= EVDEV_RC_EVENTS;
+             break;
+        }
+    }

Thanks,
Mauro

Note that "clients" refers to X clients, i.e. applications. While it's
usually trivial to add new functionality to evdev or other drivers, exposing
information to the actual client requires some protocol extension or
additions to existing extensions. While we have mechanisms in place for
devices to be labelled, we don't have anyone to actually read this
information (or even some standard on how to apply the labels).

From the implementation-side, we not only need to flag the devices in the
driver (like you've outlined in the patch below), we then need to get this
information into the X server so that the server doesn't repeat. XKB has a
per-key-repeat flag which we may be able to use but we need to also override
client-side key repeat setting (for this device only). XKB doesn't allow for
a repeat rate change request to fail, so we have to essentially tell client
they have succeeded in setting their repeat rate while using a completely
different one.
Technically, you can override the repeat setting requested by the client
if you simply send out an event when you change it back to the hardware
setting. This then looks like some other client has changed it but the
danger is that it may send stubborn clients into an infinite loop.

How much that really matters I don't know.

Letting clients know which device is an RC control at least means that the
overriding should be expected, but that brings us back to the labelling
issue.

But either way, to even get this to the "override" stage you need three
patches:
- evdev: recognise and flag the devices
- X server: introduce an API to pass this information on to the server
- X server: fixes to the XKB system to disable autorepeat for devices
  flagged accordingly and override requests to change the repeat rate.

Cheers,
  Peter
