I don't know if this is relevant, but Linus recently tried
changing the sa_restorer behaviour in the linux-2.5 kernel and
later had to back out the change. The following lines are from
recent changelogs:

http://www.uwsg.iu.edu/hypermail/linux/kernel/0301.1/0344.html
Linux-2.5.55:
Move x86 signal handler return stub to the vsyscall page, and stop
    honoring the SA_RESTORER information.

http://www.uwsg.iu.edu/hypermail/linux/kernel/0301.1/1884.html
Linux-2.5.57:
Re-instate the SA_RESTORER functionality, since it seems that some
    programs still depend on it and in fact do install a different
    signal restorer than the standard kernel version.
