rtl8169_hw_start() writes the CPlusCmd register before the ring descriptor adresses are set. Can you elaborate why it would not be enough ?
Btw the r8169 driver in 2.6.9-rcX does not advertise NETIF_F_HIGHDMA: where would a >32 bit address come from ?

I am cooking a patch for it (+ check for PCI error).
As a side note, the r8169 chipset does not like DAC to be enabled on a 32bit system. I got the usual PCI error reported while trying it.
