There is another thread titled "Intel 865G integrated graphics and XFree 4.3" that has a possible solution. It requires going back 1 or 2 revisions of your BIOS. (downgrading). I have a GX270 with the A03 BIOS and am having the same problem. Dell, however, seems to have removed references to the previous BIOS' from their website. About half-way down the thread is a link to the A01 version of the BIOS on DELL's Web Site, so the A02 might still be there, just not displayed when you search for downloads. I hope this helps you.
