Stephen,
From your description of the problem, it sounds just like writes to
PCI memory-mapped address space are being delayed and/or reordered in
the processor when in x86-64 mode.
I'd suggest to add wmb()/rmb() or (overkill) mb() calls after MMIO
stores to flush writes immediately and force

I am testing a Gigabyte 965P-S3 motherboard with onboard Marvell
88E8056 Ethernet controller (sky2 driver). The CPU is a Core-2 Duo.
Strange errors occur under moderate load with X86-64 kernel.
Surprisingly, with i386 kernel the controller runs fine without errors.
These look bus/PCI related
