I think you're right about the regularity of the tests - people using old 
machines tend to upgrade less IMO, because they mostly don't need the need 
the newest features and upgrades are generally more painful on old 
hardware.

Could do, but I'm limited to snapshots right now.

No, the machine restarts right after loading the kernel:

booting hd0a:netbsd-GENERIC (howto 0x20000)
9392308+424996+363564 [478480+465798]=0xa9e464

and at this points, the machine restarts. The kernel is -current snapshot 
few days old. Tried with GENERIC_LAPTOP and GENERIC.NOACPI as well, 
results are the same.
