(oops, late again)

You can try the hack below as a temporary fix.

It makes things way better on top of 2.6.22-rc5 + current r8169 patchkit at
http://www.fr.zoreil.com/people/francois/misc/20070619-2.6.22-rc5-r8169-test.patch

It applies against 2.6.22-rc5 too.

I should come with something else soon.
