The Fujitsu P2120 (a younger sibling to your P2040) has a DSDT method
"\\_SB.PCI0.EIO.FJEX.SMOU" to swich on and off the internal track
point. Calling this function with the argument "1" around the time [1]
of _BFS/_WAK in hwsleep.c fixes the problem here.

Ole

[1] This is perhaps a bit simplified. For various reasons, I've split
acpi_leave_sleep_state in two pieces. The "SMOU" method happens in the
first part which gets to run before devices are resumed.
