Comment 4 for bug 217504

Tested. It detects my keyboard fine, but still doesn't work. The format doesn't appear changed, either. No errors from writing to the device file. Moreover, standard keys still work through acpi_fakekey, so for some reason or another, the kernel is deciding that extraneous keys are ignored (what the kernel decides is extraneous is beyond me. Most of my special keys still work, only the blue Access IBM button doesn't).

It wouldn't be fixing the problem, but it may be worthwhile to convert or at least whitelist known problematic keys in acpi_fakekey to do fake X key events, rather than fake device key events.
