Subject2.4.9 kernel i810 module Initialization problem
 I was using the i810 module for APG video (2.4.7 kernel) with no problems.  After installation of the 2.4.9 kernel the module failed to initialize. 

agpgart.o loads fine

This is a pain because the display fails after X starts (not even char display). Disabling the i810 module fixes the problem of the display locking.

Errors Messages from the XFree86.0.log

Symbol VBEInit from module /usr/X11R6/lib/modules/drivers/i810_drv.o is unresolved!
Symbol vbeDoEDID from module /usr/X11R6/lib/modules/drivers/i810_drv.o is unresolved!
