I stand corrected on this; as I said in my previous comment, I don't think
anymore it's wise to attribute the right alt's VK to either Mode_switch or
ISO_Level3_Shift. I think I'll just use a custom xmodmap config when using
programs under wine that need that second alt key.

If you take /usr/include/X11/keysymdef.h as a reference, that comment should be
right before the /* FF80 */ line, not the /* FF78 */ one.

As for why it don't match, I would guess someone before me had this same idea
of forcing the physical right alt key to always behave the way windows expects
it to behave; that or else someone was peeved that the Mode_switch key was
being translated to a key with scancode 0, and since Mode_switch was mapped to
the right alt key in his system, decided to assign the same scancode.

None that I remember or could find in my list of installed packages (although
this system originally was either an Ubuntu 7.04 or Ubuntu 6.10, and before the
G15 keyboard was supported I had to mess with the keyboard mapping to get it's
multimedia keys to work; even though I tried to undo all my changes when the
G15 became supported, there could be leftover bits from older versions on the
config files).

A question, what are the keys you have to press to get symbols that are not in
the keyface, such as Æ? Maybe the default key to enter the third shift state
has been changed since 7.04, or you are using a mapping without third (or
higher) shift state.
