I'd be interested in your experiences w/6.0.  Would you mind testing
the onboard bge nics at the kind of loads that was causing them to
puke under 5.4?  I've got same system and as of yet not encountered
issues w/ the onboard bge nics.  The machine is also at the latest
BIOS, however, so that may contribute as well.
