when i did mine I think I had 2 qts on hand and I wanted to flush the entire system, I will admit I used Way too much, I don't think there is any old oil left in the system after 1 qt and thats probably way to much, I had like 2/3rds of a qt left over when I got done. make sure the cap is on tite/properly as I blew it off the first time and had oil everywhere, and don't pump up the pressure as high as it says you can, as it really doesn't take that much

I use Motul RBF 600 which is a DOT 4 fluid and it comes in 500 ml bottles (just slightly more than a pint). I can flush the entire system with about one bottle.
I have no idea how much is trapped in the ABS and not being flushed. The first time I replaced the stock fluid with Motul I didn't even worry about the ABS - I figured it would sorta take care of itself when I got into ABS braking at the track, as discussed in the "quote" below. To actually open all the valving in the ABS circuits in the shop you need a Tech 2.
Take a look at this StopTech site:

Under the "Technical Guides" click on "How to Bleed Brakes - The Right Way" and "Bleeding ABS, is it really as hard as it sounds?" to get some good info.
Like it says in the one link:
As much as I've got into the ABS at the track since I first put in the Motul, I'm sure I've flushed the ABS circuits completely and have Motul throughout the entire system by now. Stock DOT 3 and any of the high boiling point DOT 4 or DOT 5.1 (super DOT 4) fluids are all compatible, so I never worried about flushing the ABS with DOT 4 when first switching over.

But What If I Don't Have The Dealer Service Tool?
If you really feel the need to cycle the valves, but do not have access to a service tool (or if the dealer is not willing to loan theirs) you COULD just replace Step #2 above with "go driving and slam on the brakes a few times to make the ABS work" to purge the used fluid from the unit. This is usually NOT the most efficient nor socially responsible solution, though it seems to work just fine. You still need to bleed the car a second time, but it saves you from procuring the service tool.

I doubt this will do very much flushing of the ABS module. There is no great flow of fluid during brake operation. Just enough to increase the line pressure- then it flows back when the brake pedal is released.
