The IF-MIB I have lying around says:

  ifAlias   OBJECT-TYPE
      SYNTAX      DisplayString (SIZE(0..64))

If one were to let IOS return longer than 64 characters, as per Tims
suggestions, then it might also be necessary to adjust the above in your
local IF-MIB to avoid SNMP utilities to treat long answers as invalid. I
haven't tested anything, just thinking aloud.
