PS/2 has been surviving on the tail of the dog for too many years. During the survival years, I have wasted too much time at work trying to find KVMs that work with different PCs. Tacking on PS/2 support to modern chipsets is a ridiculous concept that causes pain. SJ was right when introducing the iMac with no legacy ports. If you need to use a legacy device, buy a USB adapter, and let the manufacturer provide customer support.

Legacy hardware support costs us all. Cheap KVMs use PS/2 and VGA which are 20 year old technologies. If Intel, Dell, HP and others had pursued the non-legacy route that they promised seven years ago, the world would be different.
