As other people already has said, it don't looks like that Hitachi is in
it for the long run, and it's not for higher speeds, I would like to
also be able to do E3/T3..... And anyway, the HD64570 is not a PCI chip,
requering additional chips to interface to the PCI bus.

The PEB20321 (Munich32) supported in that driver is a channelized
version, that not really what people are asking for.... It's also low
speed, and support only one interface if used unchannelized. I don't
remember about the Conexant chip, but I think it's channelized too.
Paul, do you know how close the PEB20321 and PEB20534 are from a
programming point if view ? But the FALC phy might be good for the T1/E1
versions.

I have look around for sync serial controllers, but keep comming back to
the PEB20534, I think that the best chip available for the job.

Soren
