I came up with this. Separate output directory option is untested.
It's not quite what you wanted but this is as close as I could get.
#!/bin/bash
#
# scripts/makei
#
# Make .i files in Linux kernel tree. You must first build a
# working kernel so this script knows which files to make.
#
# usage:
# scripts/makei [subdir]
#
# Use the optional subdir parameter to build .i files
# for just part of the source tree.
#
# Set the shell variables MAKE and OBJDIR if necessary.
#
# Examples
# If:
# Your output dir is ~/build,
# you are building the UML arch
# and you only want to build .i files in drivers/base/
# Then use:
# OBJDIR=~/build MAKE='make O=~/build ARCH=um' scripts/makei drivers/base
OBJDIR=${OBJDIR:=.}
MAKE=${MAKE:=make}
OBJDIR=${OBJDIR%/}/
find $OBJDIR$1 -type f -name \*.o |
while read fullname
do
fullname=${fullname#$OBJDIR}
name=${fullname%.o}
[ -f $name.c -o -f $name.S ] && $MAKE $name.i
done

Would -fsave-temps of gcc do the same? (Half the answer: no, it saves
the temp files in $KSRC rather than $O)
