No, we have not diagnosed the cause of the problem, beyond the swiotlb usage.
I'm adding the r8169 maintainer, linux-net and linux-kernel to CC, to pass on
your information, I hope you don't mind.
swiotlb fragmentation perhaps ?
Switching the driver to be page based on Rx would help then.

I have a Abit AB9 Pro motherboard with Intel P965 chipset, 4gb of
memory, and two onboard r8169.
Which r8169 model exactly ?
Here is some of the output from lspci -vv.
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 01)
Subsystem: ABIT Computer Corp. Unknown device 240b
05:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 01)

I think I fixed the the 5924 vs 7200 issue by upgrading to
kernel-2.6.23.13-104.fc8.x86_64.
