Ok, my X server starts now. 

When I try to switch to a virtual text console, my screen blanks.  I
can still execute a shutdown command blindly.  This implies the kernel
hasn't locked up.

There must be some conflict with the VGA controller still?  Maybe the
work around to fix the dead console at boot?

AGP support locks X kernel v2.4.9

[Nick Papadonis]

New information:

I tried compiling agp support and the i810 DRI as modules for kernel v2.4.9.
X exits out with:

(II) I810(0): Buffer map : bfb000
(II) I810(0): [drm] added 256 4096 byte DMA buffers
I810 Dma Initialization Failed


When recompiling the v2.4.8 kernel with the same configuration, X
starts fine.

I wonder what the delta between the two is?

Thats not ACPI. Linus chose to break DRI back compatibility so you can
either update your entire X11 setup, patch your kernel up by hand, or run
the -ac tree and pick the DRM 4.0 option
