I assume the reason for including the synchro-test.ko module in the standard kernel is to get people to run it :)
I realize that it's ofcourse most useful when it finds bugs, but I thought it might be interresting to get some results from people even when it doesn't find any bugs, so here are some results from a Athlon 64 X2 4400+ system running a 32bit 2.6.16-rc4-mm1 SMP kernel :
