graphics issue

[retrosoul]

hi i finally have a working hackintosh worked on it for like 2 weeks now. my specs are acer aspire x1700 small footprint nvidia 630i chipset with geforce 7100 onboard gpu 256mb ram alc888(working great all ports) 4gigs ddr2 800mhz ram sata HL dvd writer 160gb sata hdd wireless working via railink Pentium D 2.4ghz snow leo 10.6.3. everything works great except for sleep dont really care about sleep. and graphics im stuck in vesa mode with only resolutions 1024x768 and 1280x1024 both look horrible ive tried all kinds of kexts and enablers injectors etc etc. i running the 64bit kernel. if anyone has any ideas or solutions for me that would be fantastic. i would buy a new gfx card but it being small foot print platform i would need a low profile card and that means more money plus my psu is only rated 250watts max. plus im broke i really dont want to go back to windows i really like os x

thanks in advance for any help =)

p.s. my monitor is 22inches 1680x1050 thats what im shooting for.
