Just did a quick check. The current CentOS kernel (centosplus kernel
as well) seems to have code for i8042.nomux but not i8042.notimeout in
linux/drivers/input/serio/i8042.c .
You might want to give ELRepo's kernel-ml a try:
http://elrepo.org/tiki/kernel-ml
It is the latest mainline kernel that runs on CentOS.
