I tested the patch below on top of the atkbd patch, and paste still
works after s2ram

And now I see this in the dmesg

PNP: PS/2 Controller [PNP0303:PS2K,PNP0f13:PS2M] at 0x60,0x64 irq 1,12
serio: i8042 KBD port at 0x60,0x64 irq 1
serio: i8042 AUX port at 0x60,0x64 irq 12
mice: PS/2 mouse device common for all mice

so your patch did what you said it would.

Thanks Dmitry!
