This fixes the problem. After a lot of rebooting and testing the problem is definitely gone when this check is patched out and the ACPI timer override is ignored. It looks like there should be a cleaner patch than just obliterating the condition and return though.
Perhaps the code should remain as is and "acpi_use_timer_override" could be complimented by exposing the "acpi_skip_timer_override" option to the kernel command line?
This seems to have been exposed in the past: https://www.x86-64.org/pipermail/discuss/2005-April/005948.html
