2.6.28-rc1 doesn't boot, the rest of dmesgs is at:
http://decibel.fi.muni.cz/~xslaby/r8169_mac/

However I may have a hw failure or some bug overwrote my eeprom, I see this
in current mmotm:
r8169 0000:06:00.0: PCI INT A disabled
r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded
r8169 0000:06:00.0: PCI INT A -> GSI 18 (level, low) -> IRQ 18
r8169 0000:06:00.0: setting latency timer to 64
r8169: mac_version = 0x0c
r8169 0000:06:00.0: irq 43 for MSI/MSI-X
r8169: MAC address found in EEPROM: 00:00:00:00:00:00
eth0: RTL8168b/8111b at 0xffffc200042b0000, 00:00:00:00:00:00, XID 38000000
IRQ 43
r8169: mac_version = 0x0c

which looks like even in the eeprom are all zeroes now. Also 2.6.25 is
affected by this now and it worked (from_Jul dmesg).
