I have a Toshiba A210; the Realtek hardware is the same, but I am a
little surprised that there is no similiarity to the mac address
(AFAIK part of the mac address is the manufacturer's identity). In any
case, the rkill code works here
(up to date fedora 12 + compat-wireless from yesterday or the day before).

Yes, I think the gpio pins are OEM-specific.

Your patch is probably wrong - all you are doing is get some random
bits off the chip and lie to the rest of the system about being radio
is enabled.
That leads to my next question - what *is the rest* of your system?
Back in F11 I had a funny problem for a few days when I was trying
out/testing the then-new rtl8187 rfkill code Larry and Herton came up
with: I can switch off the radio and it is effective for about 1
minute - then NetworkManager decides to turn the wireless chip back
on. It turned out that hal (at least on F11, and also then, a few
months ago) needed to be taught to honour the state of the rkill
switch and be aware of it. Maybe you have the reverse problem - the
rest of your system needs to be taught not to switch it off.
As for the datasheet - no, there aren't any obvious rfkill info (or I
haven't read carefully - Larry will correct me). Realtek doesn't seem
to have a problem with e-mailing it to individuals, so a few of us has
it as well; but since they don't have it available for public download
on their web site, I assume it was sent on good faith for private
viewing pleasure.... and the terms of (re-)distribution is probably to
people who show interests in improving the driver. (instead of, say,
to competitors trying to poke holes in their hardware...).
