sn2 requires a 3.40 or better PROM
PATCH 1/1 sn2 requires a 3.40 or better PROM
The SGI 3.40 PROM includes a fix for the move of the init_task to region 5, so specify that in sn_sal.h. Unfortunately, the check for the minimum required version happens *after* the hang/MCA that is symptomatic of the bug, so this message also acts as an announcement of the requirement.
