But I haven't rebooted to it yet. Next good excuse. See below... :) I guess you can only use 3G ram because there is a big memory hole. Your HighMem zone spanned 951810 pages, 813013 of which is present. So it's not quite accurate for the OOM message "951810 pages HighMem" to report the spanned pages. Your Normal zone has 221994 present pages, while the OOM message shows "slab:206505", which indicates that the OOM is caused by too much slab pages(they cannot be allocated from HighMem zone). I guess your near 800MB slab cache is somehow under scanned.
