I dont have enough technical knowledge to answer.
All I can say is that the gpg binary required setuid-bit when I tried
using it on 2.4.31 (slackware 10.2) and that it doesn't anymore on
2.6.11.12-xenU (slackware 10.2 as a NetBSD/xen domU).

Maybe it just had something to do with memory management on 2.4.x kernel
series.
