I did a quick test and my 2 adapters (integrated and stand-alone) fail the DAC 
test.

+       if ((sizeof(dma_addr_t) > 4) &&
+           (RTL_R32(Config2) & (1<<3)) && 
+           !pci_set_dma_mask(pdev, DMA_64BIT_MASK)) {

For the above, I get 8 0 1 respectively.  So, my adapters fail because of the 
64bit slot test.  

If you like, I can try my stand-alone adapter in a 64bit slot of a ppc64 
system.
