Description of problem:
When upgrading my RH7.3 kernel from 2.4.18-3 to 2.4.18-5, I lost
direct rendering on my IBM Thinkpad A30 (Radeon Mobility). I
traced the issue to kernel modules that did not load because
they were not PRESENT in the kernel package.
Version-Release number of selected component (if applicable): 2.4.18-5
Steps to Reproduce:
/lib/modules# find . -name "radeon*"
Actual Results: When booting 2.4.18-5, chromium game is painfully slow. Graphics
are jerky and unplayable. When booting 2.4.18-3 (NO OTHER CHANGES),
chromium game plays just fine.
Ok I bet the following is the case:
you installed the i386 kernel (instead of the i586, i686 or athlon one)

have DRM support....
is my assumption correct ?
That was the problem. I didn't realize I had installed the i386
kernel for one thing but I also didn't think it mattered. Why
isn't DRM in i386? (I am by far NOT a video guru)
The DRM code internally uses CPU instructions that are not available on a
