Four-button sleeves is certainly the classic choice, but I'm not sure what the connection between long arms and number of sleeve buttons is. I have pretty long arms, too (35 to 37 shirtsleeves in RTW, depending on the maker and the amount of shrink in the) and I don't think a gapped 2-button sleeve looks any odder for the length. I have a blazer I like very much (Chester Barrie/Harrod's) with that sleeve configuration.
Now, if you think it's an odd idea to begin with, that's a different story.
