I don't know where the switchover was (sometime in the mid teen's, I 
think), but the kernel that is installed is always an SMP kernel and 
during the boot-up process, anything which is an SMP instruction is 
self-patched to be UMP instead.

Basically, when the kernel is compiled, the SMP-safe structures like 
Spinlock_t and similar are "patched" to remove the instructions that 
would normally enforce cache coherency between processors (for example).

Check the output of dmesg(1) and search for "SMP".  You'll see what I 
mean. :)
