Another problem/question:

$ cd build
$ export KBUILD_OBJTREE=$PWD
$ export KBUILD_SRCTREE_000=/usr/src/linux-2.5.13
$ alias M="make -f $KBUILD_SRCTREE_000/Makefile-2.5"
$ cp /lib/modules/2.5.13/.config .
$ M oldconfig
...

$ M installable
...

[so far so good]

$ make -f Makefile-2.5 menuconfig
[enable RAMDISK support, tweak ramdisk size, enable initrd]
...

Now, issuing "M installable" will result in nearly all files getting rebuilt.
The same happens when switching ramdisk off again. How's that?

I tried enabling/disabling many other config options and doing rebuilds but
couldn't find anything as damaging buildtime-wise as the ramdisk stuff.

Hopefully I'm causing no headaches,
