[Pc_Support] Broadcom now owns ServerWorks ... HT1000, HT2000 ...

[Bryan J. Smith <b.j.smith at ieee.org>]

I totally missed this!

Broadcom now owns ServersWorks, basically the designer of
the Intel E7200 and E7500 series, as well as its own ServerSet
III (P3/Xeon) and IV (P4/Xeon) chipsets.

Lo'n behold, they have a new set of chips for HyperTransport!

The HT1000 seems like the _idea_ "entry-level" Opteron chipset.
It has both a single PCI-X channel and a PCI/legacy PC (LPC)
on a single chip, along with SATA and their software RAID drivers
(which do run under linux).  It is a 8+8 at 1600MT (3.2GBps)
I/O interconnect that minimizes traces, EMI and cost:

For more powerful servers, or perhaps workstations, the HT2000 
adds 17 PCIe channels, another PCI-X channel and 2 GbE ports.

An interesting strategy, a little different than nVidia's
nForce Pro 2200 + 2050 which not only relies on AMD813x for
PCI-X, but you can't really use the 2050 without the 2200, and
the 2200 is like a HT2000+HT1000, but without the PCI-X.
