The solution should be simple: just creating a new "defkey.map"
with "loadkeys --mktable" (see "/usr/src/linux/drivers/char")
... until you install new kernel-sources and forget the command
(-> Murphys law). It seems quite annoying to me to configure
something again and again which could be done once and for
all (think of different source-trees).
I suggest having the default keymapping for the kernel under
"/etc/kernel/" (or something like that). The original file
could be a link into that directory (a missing file could be
created via the Makefile (?)).
(This could be a start for configuring more things than the default
keymap via files in "/etc/kernel"; but this is not my primary goal)
