Are you sure it downloads 2.6.23 to build your kernel and not the 
linux-libc-headers? Check the dependencies and what it's going to build by 
executing "bitbake <target> -g" and then poking into depends.dot...

Otherwise you can try setting PREFERRED_VERSION_virtual/kernel = "2.6.23" to 
override DEFAULT_PREFERENCE...
