(2) & (3) are not bugs for OpenSSL because only Akamai is trying to segregate the key data.
In upstream OpenSSL the intermediates are stored in the same memory pool as the key data. Thus the intermediates do not expose privileged data anywhere it is not already present.
Without addressing issues 2 & 3 Akamai's patch is not a line of defense. It does not guard against dirty memory exploits like Heartbleed, it only increases the difficulty of exploitation.
