Reverting to a 3G/1G split fixed the problems. 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.
