well...

all i can suggest is for you to try to force the resolution at start up by using this command:

"Graphics Mode"="1280x1024x32" ... just change the resolution from lower to higher... if by some reason your OS doesnt not start up dont worry this wont make any permanent change, just restart and do it again until you get the highest res possible, once you get the one you want just use the OSX86TOOLS to add a boot flag, and use the res...


if this works for you let me know...GOOD LUCK!
