r8169 MAC addresses broken

Somewhere between 2.6.24 (it would take too long to bisect) and now
(e013e13bf605b9e6b702adffbe2853cfc60e7806), 2/3 of my MAC addresses
are getting set to zero:

[ 1.533565] r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded
[ 1.539277] r8169 0000:00:09.0: PCI INT A -> Link[LNKC] -> GSI 10 (level, low) -> IRQ 10

If I set the MAC address to the correct value it then ignores packets
sent to it and I have to use promiscuous mode.
