ATI Radeon HD 4350 - no Xv - drm(4) support missing?

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

Yesterday I tried a ATI Radeon HD 4350 on NetBSD with the
xf86-video-radeonhd-1.2.5 driver from pkgsrc.

Basic 2D works fine. However, there is no Xv support.

I read up a bit on it, and it seems that the driver needs DRM support
in the kernel for Xv:
http://wiki.x.org/wiki/radeonhd%3Ar6xx_r7xx_branch

So I added
radeondrm* at vga?
options DRM_EXTERNAL
to my kernel config, compiled, found that I need agp as well, added
agp*    at pchb?
as well, compiled, and rebooted.

"dmesg | grep -i -e vga -e drm -e agp" then said:
vga0 at pci7 dev 0 function 0: ATI Technologies product 0x954f (rev. 0x00)
wsdisplay0 at vga0 kbdmux 1: console (80x25, vt100 emulation)
drm at vga0 not configured

Still no XV, as expected.

Suggestions for a next step?

Thanks,
 Thomas
