Believe you guys are talking specifically ARM so FWIW, but I remember 
for x86 that at least initially Wine and things such as VMware were 
affected by the more creative PAGE_OFFSET choices.

Both will have been as a matter of plain bugs and are supposedly long 
fixed (and I in fact believe I recall such fixing for VMware). Never had 
or as far as I recall heard of other issues back then.
