Ah, I thought I have broken hardware. I have similar problem, my mac is
initially all zeroes. When I set it up, it works until suspend. After that I
need to unbind the driver, bind it again, and it works then (mac is still the
set one).

I'm out of the notebook right now, but it is 10ec:8168:
06:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI
Express Gigabit Ethernet controller (rev 01)
	Subsystem: ASUSTeK Computer Inc. Unknown device 11f5

I used it perfectly far later than 2.6.24 (maybe 2.6.26?), 2.6.27 is yet
defunct. This should be perfectly bisectable, would you, Simon? If this is not
fixed already -- I don't think so, mmotm few days ago is still broken. Francois,
anybody, does this ring bells anywhere?
