3d acceleration with Radeon mobility



Hi, 
I have a Thinkpad A31, which uses the Radeon mobility graphics chip.  I
have installed testing, in order to get an X server that works with this
adapter.  

I have googled and searched list archives, and can't think of anything
else to do. 

Kernel is 2.4.20, with CONFIG_DRM=y, CONFIG_DRM_NEW=y,
CONFIG_DRM_RADEON=y, CONFIG_AGP=y, and CONFIG_AGP_INTEL=y. 

in XF86Config-4: 
Load "GLcore" 
Load "dri" 

Section "Device" 
  Identifier "Radeon Mobility" 
  VendorName "ATI" 
  Driver "ati" 
  Option "AGPMode" "1" 
EndSection 

(I have tried both "ati" and "radeon" for the Driver; same results.) 

at boot: 
Linux agpgart interface v0.99 (c) Jeff Hartmann 
agpgart: Maximum main memory to use for agp memory: 439M 
agpgart: Detected Intel i845 chipset 
agpgart: AGP aperture is 64M @ 0xe0000000 
[drm] AGP 0.99 on Intel i845 @ 0xe0000000 64MB 
[drm] Initialized radeon 1.1.1 20010405 on minor 0 

In X log: 

(II) RADEON(0): Acceleration enabled 
(II) RADEON(0): Using hardware cursor (scanline 4208) 
(II) RADEON(0): Largest offscreen area available: 1408 x 1080 
(II) RADEON(0): X context handle = 0x00000001 
(II) RADEON(0): [drm] installed DRM signal handler 
(II) RADEON(0): [DRI] installation complete 
(II) RADEON(0): [drm] Added 32 65536 byte vertex/indirect buffers 
(II) RADEON(0): [drm] Mapped 32 vertex/indirect buffers 
(II) RADEON(0): Direct rendering enabled 

However, gxlinfo | grep render says: 
direct rendering: No 
OpenGL renderer string: Mesa X11 

and glxgears reports frame rates ~200FPS 

Can anyone shed light on this? 

thanks!
