This thread has me a bit concerned, as I'm using Dell PowerEdge
servers which use on-board versions of these NICs:

Broadcom NetXtreme II Gigabit Ethernet Driver bnx2 v1.5.11-rh (June 4, 2007)
eth0: Broadcom NetXtreme II BCM5708 1000Base-T (B2) PCI-X 64-bit
133MHz found at mem da000000, IRQ 169, node addr 0019b9b993a7

Would they be subject to this issue as well?
