The DSDT shows that there are no programmable IRQs
in IOAPIC mode on this machine, so it is unlikely that
there is an ACPI interrupt routing issue.
It is more likely that the problem is in one of the devices (above)
using IRQ21. I assume that the touchpad is uhci_hcd:usb7?
What does "lsusb" show on this machine?
Of course I'd recommend trying to reproduce the issue
after excluding "ndiswrapper" from the configuration.
