Ah, OK, so I need to force it to use Set 3 by default.  Passing atkbd_set=3 on it's own didn't seem to work, (only works with i8042_direct).

Seems like it, yes.

All I can tell you is a translation of what is written on the scancode 0x87 key on this particular keyboard:

'Hiragana/Roma_characters'

I can't translate the characters on the other keys.

However, somebody else might be able to - I found this diagram of the keyboard:

http://www.pfu.co.jp/hhkeyboard/kb_collection/ibm5576-002.gif

The legends on the bottom row of keys are exactly the same as on my keyboard, and from left to right, they have the following functions:

Control
ALT, (it says, 'Kanji/Katakana/Kanji???', but works as ALT)
Scancode 0x85
Space bar
Scancode 0x86
Scancode 0x87, (it says, 'Hiragana/Roma characters')
ALT GR
Control

Sorry I can't be more help than that :-).

Ah, OK, cool.
