Current Linus mainline has

commit 8c9a9dd0fa3a269d380eaae2dc1bee39e865fae1
Author: Alan Cox <alan@redhat.com>
Date:   Fri Aug 15 10:39:38 2008 +0100

    tty: remove resize window special case

which might have fixed this after 2.6.27-rc3, so testing
ftp://ftp.kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.27-rc3-git6.gz
would be most interesting.

We should hunt down the problem and get 2.6.26.x fixed up too.

Thanks.
