Changing PAGE_OFFSET this way would break at least Valgrind (the latest release 3.1.0 by default is statically linked at address 0xb0000000, and PIE support does not seem to be present in that release). I remember that similar changes were also breaking Lisp implementations (cmucl, sbcl), however, I am not really sure about this.
it also breaks some java versions, so we use 3:4 Gb split in OpenVZ, but redhat still uses 4:4 in enterprise version, so number of such applications should decrease :)
