BTW any reason why you appear to have SACK off?

default distro setup, Fedora 9 and Fedora 8. No extra tweaking that i'm 
aware of.

It's probably a side effect of their turning on syncookies in /etc/sysctl.conf :-/

I thought we added code that would allow enabling those options
even with syncookies enabled?  There is code in net/ipv4/syncookies.c
function cookie_check_timestamp() to handle this.

Of course this is a recent addition, so if either side doesn't
have that change.
