asterisk users - Nov 2009 - best channel driver for 1.4.x and beronet/junghanns 4BRI?

Hi,

What is the best channel driver to use asterisk 1.4.x with a 4BRI isdn
card from Beronet or Junghanns (same hardware, different pcid)?

Are these cards now supported by plain (non-patched) dahdi/zaptel
modules?

Thanks,
