James,

My A22p has the same problem. I have had to use the basic (VESA) video
driver whenever installing Fedora. A couple of weeks ago I finally found
the 'gtf' utility which computed the required modeline. I wrote a custom
xorg.conf file for Fedora 13. If Fedora 8 uses xorg (I don't remember),
it should work for you.
