Being a conservative soul, I tried that, passing the -n flag to make:

     [root at woof ltmodem-2.6-alk-4]# make -n -C /lib/modules/`uname 
-r`/build SUBDIRS=$(PWD) modules_install
     -bash: PWD: command not found
     make: Entering directory `/lib/modules/2.6.6-1.435/build'
     if [ -z "`/sbin/depmod -V | grep module-init-tools`" ]; then \
             echo "Warning: you may need to install module-init-tools"; \
             echo "See 
http://www.codemonkey.org.uk/docs/post-halloween-2.6.txt";\
             sleep 1; \
     fi
/==>rm -rf /lib/modules/2.6.6-1.435/kernel
|==>rm -f /lib/modules/2.6.6-1.435/build
|   mkdir -p /lib/modules/2.6.6-1.435/kernel

In particular, creating that circular symlink must be wrong, which gives 
me pause wrt the rm -rf /lib/modules/2.6.6-1.435/kernel.
