Maybe a workaround for some people:

I had a similar problem here, using the Dapper i810 driver with a 82845G/GL integrated graphics. X started up fine, but entering into terminal mode with Ctrl+Alt+F1 and back again caused infinite respawn.

From my Xorg.log:

Fatal server error:

Changing the "Internal Graphics Mode Select" bios setting from 1MB to 8MB solved the problem for me.
