If that is what Apple says then I suspect it would be the case with linux from
the same video card. The high pitched sqeal generally means that you have
exceeeded the valid resolutions. Try configuring for 800x600, and see if that
takes care of the sqeal, and gets you into X. What error messages are you
getting besides the normal messages about unusable modes being deleted? Also
try setting up you XF86Config with only 1 resolution at first, then add more
until it breaks.
