Dmitry, you're just making things up.

I have in front of me a Core i5-670. You can't get much newer than that.
And yes, it has a PS/2 connector at the back. And lookie here:

[ 1.756777] PNP: No PS/2 controller found. Probing ports directly.
[ 1.760645] serio: i8042 KBD port at 0x60,0x64 irq 1
[ 1.762087] serio: i8042 AUX port at 0x60,0x64 irq 12
[ 1.763591] mice: PS/2 mouse device common for all mice

so let it go. You're wrong. PS/2 is a legacy device, and exactly like the
legacy IO memory region in 0xa000-0xffff (or the motherboard IO port
region 0x00-0xff) it may not be mentioned by the BIOS tables. But it's
still there.

This is also why I think it _would_ be acceptable to say that if you boot
from EFI, you have to find the PnP devices. The whole (and only, as far as
I know) point of EFI was that "legacy-free" thing.
