Now I found a thread about tcp window scaling affecting the loading of
some sites but I fail to load the above site with
/proc/sys/net/ipv4/tcp_adv_win_scale set to 6 and 2 under 2.6.17.1
whilst it works just fine with the /proc entry set to either 7, 6 or 2
under 2.6.16.18.

You must have misread those threads.  To work around the problem,
you don't modify tcp_adv_win_scale, instead what you do is set
tcp_window_scaling to 0.

Yup. Must've. Just tried it now and setting tcp_window_scaling to 0
makes the site load. Sorry about that. Looks like I'll have to remember
to make sure that gets set to zero on any servers I wind up having to
upgrade to 2.6.17 and beyond.

Bugger. :/
