If you are running in PAE mode then you should try modifying the kernel file
drivers/net/tg3.c and changing any '#ifdef CONFIG_HIGHMEM' to '#if 0'. It
may also be worth doing some tracing around the code that does
pci_set_dma_mask() to see what path you are taking there and what mask the
driver is choosing to set.
