[maemo-developers] Mapping the N900 keyboard?

[From: Qole]

Now that the N900 has been released, I will post this question on
maemo-developers, in the hopes that some Nokia devs can help me here.

I would like to know how to remap the keyboard on the N900. I've received
some help from Marius Gedminas, as you will see below, but I'd like to know
how to map the keyboard permanently, without having to run xkbcomp every
time.

Here is the help that I've received so far:

(I have already replied with the following:

Replace
       type= "FOUR_LEVEL",
       symbols[Group1]= [       Right,       Right,       Tab,       Tab ]
with
       type= "PC_FN_LEVEL2",
       symbols[Group1]= [       Right,       Tab ]

and you will retain the ability to highlight text with shift-right arrow.)
