[PATCH] prevent swsusp with PAE
PAE + swsusp results in hard-to-debug crash about 50% of time during
resume. Cause is known, fix needs to be ported from x86-64 (but we can't
make it to 2.6.18, and I'd like this to be worked around in 2.6.18).

(For now, swsusp is incompatible with PAE aka HIGHMEM_64G on i386.
82

we need identity mapping for resume to work, and that is trivial

to get with 4MB pages, but less than trivial on PAE).
