This can be worked around by setting "hw.acpi.event_driven=1" but I want to make it work by default. The event_driven sysctl is not a full solution because it uses DELAY heavily. To reduce the load in DELAY, I implemented burst mode support. However, since no open source EC code uses burst mode, it is unknown how good its hw support is. So my code has lots of tests of your EC and I need the dmesg output from it to know how to proceed from here. That's why I need wide testing. The patch is not a complete implementation but it should help identify any hw problems in burst mode support. I won't put it into the tree without making sure it can fall back correctly.
