I don't know offhand, but in principle anything that has PCI and a southbridge (not all PCI platforms have one, e.g. Broadcom SWARM and BigSur are legacy-free) can have an 8042 wired. Ideally probing for 8042 hardware should be done by platform code and the driver's init code would not be called at all if there's no 8042 present, similarly to how e.g. RTC is usually registered.
