It can't be done. As you have found, 100,000,000 is the absolute limit. MS never documented it (AFAIK), but the limit has been known for a long time: an answer from 2004.
On previous versions of Windows, trying more than 100,000,000 crashed the OS :)
On my XP and Vista machines, trying more than 100,000,000 rows limits the size to 9,999,999.
