This should really read 1) The SAREA is likely to be used by mixed 32-bit / 64 -bit clients and servers. (If I understand things correctly, the kernel never accesses the SAREA). However the sarea structs are _not_ safe against this. The layout of the sarea structures must be identical for 32- and 64-bit clients, and one should probably use the fixed size types (uint64_t, uint32_t etc.) and be very careful with alignment.
