Need some advanced XFree86 + DRI help.  I have a Thinkpad T40 with a
Radeon Mobility chipset that refuses to do 3D acceleration.  It runs
Gentoo 1.4.  I put in a different hard drive and loaded RH9, but still
had no 3D acceleration.

  gentoo-box# glxinfo | grep rendering
  direct rendering: No

  redhat9-box# glxinfo | grep rendering
  direct rendering: No

Funny thing is that Knoppix 3.3 boots up with 3D acceleration working
perfectly on this laptop.  

  knoppix-box# glxinfo | grep rendering
  direct rendering: Yes

Of course, this is the OPEN SOURCE approach to supporting this hardware
via the dri.sourceforge.net project.  The proprietary ATI drivers for
Linux _do_not_support_ this particular chipset.  So, as tempting as it
sounds, `emerge ati-drivers` _does_not_ fix the problem here.


Specs (I'll be glad to send any other configs or output):

IBM Thinkpad T40, Pentium M 1500Mhz, 512MB RAM
ATI Radeon Mobility M7 LW (w/128MB RAM)
Gentoo 1.4, Kernel 2.4.20, 2.4.22, 2.4.25
xfree 4.3.0-r5 && xfree-drm 4.3.0-r7


I'm wondering if we have any XFree86 and/or DRI wizards on the list. 
Any ideas?

Thanks,

...Kevin
