>Description:
I am trying to run X11 on NetBSD i386 on a laptop with an ATI Radeon IGP320M graphics card (approximately from 2002).
I can get it to work with the "radeon" driver, but that requires manually entering DDB (through "boot -d") and setting "w radeon_pci_ignore_r100_r200 0".

I'm asking for a build-time option (something like "option RADEON_R100_R200") that I can just set in my kernel config instead of manually typing "w radeon_pci_ignore_r100_r200 0" in on every boot.

Using "radeondrm" instead doesn't work with the X11 from the distribution sets. It needs the X11 from pkgsrc with 'x11/xf86-video-ati6' (also from pkgsrc). According to https://www.x.org/wiki/radeon/, version 7 of xf86-video-ati removed support for UMS. If the radeondrm driver only can use UMS, then I assume that's why it doesn't with the distribution X11.

So "radeon" both works better on my hardware and doesn't require installing obsolete X11 modules from pkgsrc.

There is still the issue that the ring test fails and GPU acceleration is turned off (see [     5.660226] in the attached dmesg). But the system is usable (and faster then "radeondrm" somehow) even in this state.

Here is dmesg output when booting after "w radeon_pci_ignore_r100_r200 0":

>How-To-Repeat:

>Fix:
For now: Add a build-time option to enable "radeon" driver for R100 graphics card.
