Okay, the final piece, userspace:

/sys/bus/acpi/devices/QEMUVGID:00/modalias gives:
acpi:QEMUVGID:VM_GEN_COUNTER:

modinfo -F alias vmgenid.ko gives:
acpi*:VM_GEN_COUNTER:*

udev src uses fnmatch.

Bash confirms a match:

$ [[ "acpi:QEMUVGID:VM_GEN_COUNTER:" == acpi*:VM_GEN_COUNTER:* ]] &&
echo matches
matches

So I think with ACPI_ID_LEN --> 16 we are good to go.
