I have a Dell 700m with an i855GM chipset. X crashes with a "Bad V_BIOS checksum" warning followed by a "vm86() syscall generated signal 11." error when I try to use a dual-head configuration. Other configuration info: Fedora Core 4 kernel 2.6.15-1.1833_FC4 xorg-x11 6.8.2-37.FC4.49.2 I don't know if this is a cause of the problem or not, but I use the 855resolution program (http://perso.wanadoo.fr/apoirier/) to add a 1280x800 mode to the video bios. I found related bugs, but none with this exact problem.

This bug sounds very similar to #3105. You should try my test driver for 6.8.2 that's available here. http://www.fairlite.demon.co.uk/intel.html
Excellent! i810_drv.o from the link you provided fixes this problem. I didn't do alot of testing, but everything seems to work fine, even coming back from suspend to ram it still works. The dual-head display works with the xorg.conf file I attached (using the multihead layout of course). I can try specific tests if that would help, else I would consider this fixed...

As I mentioned, the driver on your website fixed this problem. But the most recent xorg update (in FC4) breaks things again. I tried to get the updated driver from your website, but I get a 404 error. I realize this is probably a Fedora problem, but before i complain to them again I want to make sure.
