Yes, rtl8187B is in recent kernel; it is still a bit buggy but the two
external links - cuervo's link to an old version of the vendor driver
ported forward and there is a newer vendor driver, but neither
supports the latest kernel - and that's not entirely bug-free either;
there has not been much activities at the sourceforge link, so that's
really just for reference.

I would say add these two pieces of information:

- it is known that rate-control doesn't quite work with either rtl8187
or rtl8187b. "iwconfig rate <somerate> fixed" may work better under
some circumstances.

- we don't support rtl8187B with a product id 0x8198 (in some very new
toshiba laptops) yet. It seems the vendor driver works to extent, but
report against the community driver (by adding the id) has been
inconclusive.
