The cards are MT23108. ibdiagnet -lw 4x -ls 2.5 shows no fabric errors also confirmed on my silverstorm switch.
The rack contains X4100 and X4100 M2 servers. The M2 servers do not exhibit this behavior, they're showing 750MB/sec local loopback on an IMB pingpong run. Errata 56CLK is enabled in the bios and mostly all other PCI-X or HT Bridge settings are set at they're defaults (ie auto) I fiddled with a few of the settings, but they neither made it worse or better. So i'm really not sure what option got changed when i reset the bios to optimal defaults, but i wish i did...
