After an annoying battle with Gallium, KMS, firmware, etc. on my

someplace, but I'm not sure how to go about adding it. For starters,
where does it belong, in Post LFS or in Xorg? I'd be happy to add a
page, but I'm not at all familiar enough to do so yet.
For instance, I have a card that is identified as an HD 5400 Cedar Pro
(it was cheap and I have no need for a monster graphics card). After
building in first one at a time, and then all of the CEDAR_*.bin files,
I was still greeted with a ~30 second delay on boot up, and no DRI2 each
time. As a last ditch attempt, I attempted to include all of the bin
files in the radeon subdirectory and found that oldconfig choked on it
and prompted me. I randomly built in the first 9 files (alphabetically)
which included the CEDAR blobs and it worked, but I have absolutely no
idea why! Everything I've managed to find has told me that building in
the CEDAR_*.bin files should be enough.
I plan to reduce that list later, but I'm on a Java trip now that Gnome
is working sufficiently well. Perhaps I've simply lost my Google touch,
but I'm not convinced that good documentation even exists yet! Anybody
got a pointer? Perhaps a link in the xorg configuration will handle it
until concise documentation can be produced for the book? Maybe it would
be better to recommend building the vendor DRM driver only as a module,
and to install all the firmware in /lib/firmware (I haven't actually
tried this, but I found documentation that said Xorg would tell you the
needed file in the log if DRM is a module)? Suggestions?

I personaly find it easier to build everything but the stuff that is
necesary for boot as modules since I want to run one kernel on several
machines. I did not notice any speed performance with those builtin,
only failures with Xorg (long time ago, when I was still fresh).
And since firmware is not available in kernel source tree, thus it can't
be builtin by default, I agree to suggest building DRM drivers as
modules, since it is lot easier just to put firmware in /lib/firmware
instead of rebuilding whole kernel. That is the problem with newer
nouveau cards, since they require firmware not in the kernel, too.
