Gary’s OD&D House Rules:
For a score of 15 or over:
STR: +1 to hit and +1 to damage if a Fighter
INT: +1 1st level m-u spell
WIS: +1 1st level cleric spell

CON: +1 HP per HD (same as a Fighter class gets, +2 if a Fighter)
CHA: +1 (positive) on reaction checks
HPs: Characters are only unconscious at 0 HPs. For each level a character may have a minus HP total equal to the level, so a 1st level PC is dead at -2, a 2nd level at -3, etc.

These help spread a little love around the prime requisites, fix the oddly incomprehensible rules for Constitution, and gives Charisma a front-end effect as well as a back-end effect (Charisma already had a really important role in governing follower loyalty in OD&D).

The rules mentioned in this post are at the bottom of the first post on that forum.
