No, I don't know the answer.
I suspect it's historical cruft: The first Acorn computers that Linux was ported to (Archimedes series) used a proprietary keyboard interface. The mapping on RiscPCs was probably chosen to make the codes compatible with those of the (now obsolete) Archimedes machines.

I actually tried deducing the lowlevel keycode mapping for my script by looking at this and drivers/char/pc_keyb.c, but finding out the mapping this way is, erm, "non-trivial". :-/ Another point: I don't think it's necessary to convert *all* of the i386 maps for the RiscPC, given that RiscPCs are only really used in some European contries and "down under". The following maps would be sufficient IMHO: i386/azerty/be-latin1.kmap i386/azerty/be2-latin1.kmap i386/azerty/fr-latin0.kmap i386/azerty/fr-latin1.kmap i386/azerty/fr-pc.kmap i386/azerty/fr.kmap i386/qwerty/it-ibm.kmap i386/qwerty/it.kmap i386/qwerty/it2.kmap i386/qwerty/nl.kmap i386/qwerty/pc110.kmap i386/qwerty/uk.kmap i386/qwerty/us-latin1.kmap i386/qwerty/us.kmap i386/qwertz/de-latin1-nodeadkeys.kmap i386/qwertz/de-latin1.kmap i386/qwertz/de.kmap i386/qwertz/fr_CH-latin1.kmap i386/qwertz/fr_CH.kmap ...plus the include files needed by these.
