On Wed, Feb 25, 2009 at 10:47:07PM -0500 I heard the voice of
Steve Wills, and lo! it spake thus:

For a data point, I have

re0: <RealTek 8168/8168B/8168C/8168CP/8168D/8111B/8111C/8111CP PCIe
     Gigabit Ethernet> port 0xdc00-0xdcff mem 0xfdfff000-0xfdffffff
     irq 19 at device 0.0 on pci2
re0: turning off MSI enable bit.
re0: Chip rev. 0x38000000
re0: MAC rev. 0x00000000

on a recent 7-STABLE (if_re.c,v 1.95.2.41) which is working OK.  I
have gotten a few Tx interrupt watchdog timeouts, which I don't recall
seeing in any quantity before, but they don't seem to cause any
problems.  It was previously on a ~Dec 2007 RELENG_7 and worked fine
there (and had MSI enabled, as well).
