Some recent hardware has trouble with routing PS2 port interrupts while the interrupt controller is in legacy routing mode. This patch adds a config mechanism (via "etc/ps2-poll-only") to force the PS2 code into a polling only mode so that interrupts are not required.
It is not recommended to use this polling mode on hardware that does properly support PS2 irqs, because some very old (DOS-era) programs depend on the BIOS PS2 irq behavior.
FYI - this patch was pushed.
