Lateral fricative origins

Does anyone know how Welsh <ll> (voiceless lateral fricative) developed
historically? Or how lateral fricatives developed in any other languages?
They aren't very common, and I *believe* that in the Bantu languages they
derived from palatal stops or fricatives.
I know that in Sino-Tibetan Gurung a lateral fricative developed from
a /kl/ cluster, which is how it is still realized in some dialects.
Doing some reading on the Romance languages, I came across an interesting
factoid about the Northern subdialect of Logudorese Sardinian. In
Logudorese in general there is a neutralization of /l, r, s/ syllable-
final, such that IIRC they merge as /s/ before voiceless stops and as
/l ~ r/ before voiced stops and sonorants. In Northern Logudorese,
however, /l, r, s/ plus stop have neutralized in a different manner:
-l/r/s + p- > pp (or jp)
-l/r/s + b- > vv
-l/r/s + t- > LL (voiceless laminodental lateral fricative)
-l/r/s + d- > L\L\ (voiced laminodental lateral fricative)
-l/r/s + k- > xx (voiceless (post)velar fricative)
-l/r/s + g- > GG (voiced velar fricative)
Note that this innovation occurs not only medially, but also across word
/kanE/ 'dog' /sOx xanEs/ 'the dogs'
I assume that the same holds for words beginning with /t, d/, but the
article I read didn't give any examples.
