I can confirm that (if I'm understanding what you're saying there).

curty@einstein:~$ lspci | grep -i ethernet
06:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06)

curty@einstein:~$ uname -a
Linux einstein 2.6.32-5-amd64 #1 SMP Thu Nov 3 03:41:26 UTC 2011 x86_64
GNU/Linux

The kernel driver (r8169) is very flakey, with frequent connection
losses requiring restarting networking and poor throughput (is that the
correct term for diminished download speeds?).

Why not use the autorun.sh script provided with the tarball?

I don't have a file /etc/modprobe.d/blacklist.
I have /etc/modprobe.d/blacklist.conf

Using debian squeeze here.  But the above file says "it does not affect
autoloading of modules by the kernel," so I wonder if your technique
would be effective.  The autorun.sh script simply removes the module
('rmmod 8169', if it's loaded) and renames it r8169.bak.
