Hey, give me some credit :)

[asuardi@dolphin linux]$ /bin/pwd
/usr/local/src/linux-2.5.25/include/linux
[asuardi@dolphin linux]$ cat compile.h
/* This file is auto generated, version 1 */
#define UTS_MACHINE "i386"
#define UTS_VERSION "#1 Sat Jul 6 02:27:10 CEST 2002"
#define LINUX_COMPILE_TIME "02:27:10"
#define LINUX_COMPILE_BY "asuardi"
#define LINUX_COMPILE_HOST "dolphin"
#define LINUX_COMPILE_DOMAIN ""
#define LINUX_COMPILER "gcc version 3.1"

I'm saying "doesn't happen for me" because it doesn't happen.

I've been compiling kernel as non-root (and well, of course
  installing as root) since 1996.

I'll admit I checked only the files I cut'n'pasted last mail,
  well let's be honest then...

[asuardi@dolphin linux]$ /bin/pwd
/usr/local/src/linux-2.5.25
[asuardi@dolphin linux]$ find . -user root -print
[asuardi@dolphin linux]$

See, *no* root-owned files here. Usual process is

  * save previous kernel's .config
  * zap previous kernel tree
  * untar the previous kernel tree in /usr/local/src
  * patch -p1 it with current kernel patch
  * create new kernel tarball
  * copy over saved .config
  * make oldconfig
  * make dep; make clean; make bzImage; make modules
  * (wait for next kernel patch ;)

Ciao,
