2.2.19, agpgart, dri --> @$#%^

[Matthieu Paindavoine <mpaindav@arinc.com>]

Hello,

I have recently recompiled my kernel (obtained from .deb source package,
2.2.19-6) to include support for agp

So I added CONFIG_AGP, CONFIG_AGP_I810, CONFIG_MTRR, CONFIG_DRM,
CONFIG_DRM_R128 to my kernel config files, compiled, reboot, and the
boot hangs with a 

"Unable to handle kernel null pointer ...".

I've recompiled the old version, and it works again. So it seems adding
these options cause the kernel to hang.

Has anyone used these options successfully?

(I have an ATI Rage Mobility, Intel Solano (I815) chipset)

Thanks for your suggestions.

Matthieu
