Ok that is a Hynix chip, no other chips of that bran is currently supported, but the data-sheet is available here:
http://www.datasheetcatalog.org/datasheet/hynix/HY29F002TT-55.pdf

So it shouldn't be to much trouble to get it working.

It is a 256KB 5v PLCC32. I think it is parallel but you should check with the flashrom developers to confirm this.
You probably want to desolder it and solder on a PLCC32 socket and get a compatible spare to experiment with, so that you do not brick you board. If you are no skilled with a solder iron i highly recommend paying some one who is.

Yep, that's right. LPC and FWH chips are always 3V3, and very rarely
smaller than 4Mbit or 512kbyte.

Hey Anders,
I can help out with coding and testing support for the GA-6VX7-4X. Do
you have a patch with the code you have done already, so we don't
duplicate efforts? I've got datasheets for the north and south
bridges, so it shouldn't be too difficult to include support for this
board. Let me know how I can help.

Thanks,
David

Hi

Grate, I'll send so the patch in a day or two.
At the moment it sets up most of the config before ram init, the SMBus code 
is about half done.
