Anything that does it through HAL when HAL gets updated, I suppose.
I don't really care for the network management GUIs, I have never seen one that worked properly, so I dropped them all for good. The UIs I use are wpa-supplicant's config file, iproute and friends, and Debian's ifupdown crap.
The only UI I trust enough to touch rfkill control on my machines is the kernel itself (rfkill-input is an UI), so I guess you will have to ask someone else about it normal user-level UIs and GUIs for rfkill :( Probably in the linux-wireless ML, instead of here in LKML.

thinkpad-acpi.experimental=1 in the kernel command line should do it.

It is in my TODO list, so you don't need to bother. But if you do, here are my requirements for patches to be accepted, so that you don't waste your time:
1. Do it based on thinkpad-acpi in Linus' mainline, and give the patch a proper title prefix ("ACPI: thinkpad-acpi: "), title and commit message. Sign it off, and CC me.
2. UPDATE THE DOCUMENTATION ALONG WITH THE CODE, in the SAME patch. That means Documentation/laptops/thinkpad-acpi.txt.
Plus the usual "test it first", etc. But it will be an extremely trivial one-liner patch to the code, so I wouldn't worry much about that ;-) It is the doc update that will make up most of the patch.
