Sounds like even with that starter size, you're going to be underpitching by quite a bit.
Assuming a 1.045 OG and a 5 gallon batch, you'll need about 158 billion cells according to yeastcalc.com
. Using a viability date of 2/8/12 for the yeast, viability is estimated to be 16%, or 16 billion viable cells from the original 100 billion. A .65L starter using intermittent shaking, will bring you up to roughly 57 billion, which is about 100 billion short of what you really need.
You can go with it, knowing you'll likely have stressed yeast, and it'll probably turn out fine if you give it a good 4-week primary. The fact that you made the starter does help since the yeast you do have are awake and ready to go. Howerver, if you haven't started brewing yet, I'd suggest you do another step up with a 1.2-1.3L starter so you know you'll be pitching at the proper rate.
I wouldn't worry about the lack of krausen. That's not at all uncommon.
