Hello, colleagues,

I'm trying to enable an AGP slot (again) on my Maple board (dual PPC970FX
board, with CPC925 (U3H) north bridge).

=A0For now I'm stuck with a problem: I use radeon card, drm-radeon driver=

 with

KMS.

If I force drm-radeon to think about a card as about PCI card (by comment=

ing

corresponding lines in drm_radeon_kms.c), everything works, I get
framebuffer, working X11, etc. If I enable agpgart-uninorth driver
and RADEON_IS_AGP flag in drm driver, I get an Oops early during the
bootstrap. Relevant part of the log (I can send full dmesg of normal
bootstrap or this oops on request, if that would help).

For future reference, you can disable AGP by loading radeon with the
agpmode parameter set to -1, e.g., radeon.agpmode=3D-1

No need to edit the source.
