The mplayer patch is to make it use LDT_AUTO_ALLOC.  The ldt
fiddling code (taken from wine) doesn't use LDT_AUTO_ALLOC,
so I had to make it use it.  See if you can patch wine to
use LDT_AUTO_ALLOC; it shouldn't be calling i386_set_ldt()
any other way.

BTW, you only get the first 10 occurrences of static ldt
allocation warnings from the kernel.  It stops printing
them after 10.

Good.
