To the end of /boot/grub/grub.conf I added the line:
psmouse.proto=imps
Well the psmouse.proto=imps needs to be added to one of the kernel command lines in grub.conf, not on a line by itself.
I use a msi wireless keyboard and mouse on a kvm and the only time I see erratic mouse behaviour is when the batteries have gotten low and I put in a full charged set.
