I couldn't run this because my libc requires 2.6 kernels.
But I've managed to run wine with a game called 'Align-it!', and I have the following result:
""" ~/tmp/ egrep -c 'modify_ldt' wine-strace.txt 46 ~/tmp/ """
I've checked the calls and none has failed. Not sure how good this test is though.
Maybe it could be more tested in -mm?

Oh, that's a good tip.
Thanks a lot,
