I have actually used pawn=32 since quite a long time (if I recall correctly,
Gothmog 0.4.6 and later use pawn=32, older versions used pawn=64), and I haven't
seen any bad effects of the low resolution.  The internal resolution in my
evaluation function is pawn=128, but I divide all scores by 4 before I return
them.
