tc1100 - The other WMI driver I maintain (the one that I’ve never even had the hardware for, let alone set eyes on, which always makes it ‘interesting’ to work on).
I’ve posted patches to add rfkill support to this driver to the linux-acpi mailing list. If you:
1) Have the hardware
2) Can compile your own kernel
Then please grab the patches, try them out and let me know if they work, or break horribly.
