About 500 out of 700 mainboards sold today has a PS/2 port which is probably due to prevalence of legacy devices and usbhid limitations. Similarily many boards have serial and parallel hardware ports. In all diagrams detailed enough to show these ports I have seen them attached to the LPC bus.
Do these boards have a TPM? Remember that the TPM requires special LPC bus cycles. Even if so, the TPM LPC bus wait states are less than a usec. My thought is that it's unlikely that any device (serial port, mouse, keyboard, printer) will be adversely affected. -- To unsubscribe from this list: send the line "unsubscribe linux-security-module" in the body of a message to majordomo at vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
