PS/2 is just as hotplug as USB for keyboards and mice, at least on Linux. Try it. Unplug your PS/2 keyboard while the system is running and then plug it back in. Everything works.

PS/2 hotplug blows a fuse on my motherboard. YMMV, but it's risky.

it varies motheboard to motherboard, but I can definantly attest that hotplugging PS/2 keyboards can pop fuses on the motherboard (it depends which pins connect first, just the right combination will cause problems)

back when I worked PC repair I repaired dozens of machines with this exact problem (interestingly the manufacturers expected service was motherboard replacement)

Weird. It's worked fine on all my machines, I didn't even know it could cause problems. Nice to know, I guess.
