Must admit that I've not looked at all in the implementation of either
SLLocate or drmSLLookupNeighbors.

That said it seems that none of the three files
(xf86drm{SL,Hash,Random}) has been build as a program for a while. Maybe
we could split it out as a standalone test and let it churn at make
check time ?
