James Harr [off-list ref] :
[...]

The driver you sent gives me an error when I try to compile and load it with 
2.6.11.11:

The driver that I sent you builds with 2.6.12-rc4. Please try 2.6.12-rc4 +
the aforementioned driver.

If it still crashes (?), tell if your .config matches:

CONFIG_R8169=m
CONFIG_R8169_NAPI=y
# CONFIG_R8169_VLAN is not set

or:

CONFIG_R8169=m
CONFIG_R8169_NAPI=y
CONFIG_R8169_VLAN=y

An history of the commands issued to set the config before the crash
would be welcome too.
