How many displays can I power from my GeForce 555m laptop?

I just ordered two 27" Korean IPS LCD's, each with a max rez of 2560x1440. Can I power both of these at the same time from my laptop?

I have a laptop with a GeForce 555M GPU, and an i7-2860QM/HD3000 GPU. This laptop has an HDMI 1.4 and a VGA port. I have some HDMI 1.4 cables, but from what I understand I still won't be able to run even a single display at 2560x1440@60Hz because there is some kind of hardware missing from the display that will prevent this over HDMI.

I also ordered a SIIG USB 3.0 to DisplayPort adapter. This will work for a single display. Would I be able to get two of these to run both 27" LCD's at the same time? What if I pair the SIIG with something like this:

Regarding HDMI 1.4: No, HDMI does not have enough bandwidth to support resolutions beyond 1920x1200 @ 60Hz

Regading the SIIG: First does your Korean IPS from ebay have DisplayPort inputs? If not the SIIG hardware may not work in your scenario.

Yes, my display has DisplayPort. Curious if I can have multiple SIIG devices at the same time. Anyone know this?

Not too helpful. Laptop video card is not upgrade-able, and a new laptop is not an option right now. I'll just continue using the displays with my desktop. Was hoping to be able to use my laptop and never have to switch to the desktop to alleviate some syncing.
