6 As I mentioned in my reply to Michael Mol, building mesa with the
7 "llvm" USE flag does the trick.

9 It appears the web pages http://www.gentoo.org/doc/en/xorg-config.xml
10 and http://www.gentoo.org/doc/en/ati-faq.xml may be out of date. The
11 video card shows up under lspci as...
12 "ATI Technologies Inc RV280 [Radeon 9200 PRO]".

14 According to the Gentoo web pages, it doesn't need a firmware blob at
15 all. However, when booting, the PC said something about loading an R200
16 blob. It sat there for a minute, timed out, and went on to a standard
17 VGA display. I emerged radeon-ucode and it came up with 62 files,
18 including R200_cp.bin. I stuck that file into the
19 "[*] Include in-kernel firmware blobs in kernel binary"
20 option in the kernel, rebuilt, and it appears to work. Since this is an
21 actual gentoo.org webpage, and not a wiki, I'll file a "documentation
22 bug" at bugs.gentoo.org.

24 The "torture test" will come this evening. I'm a paying subscriber to
25 NHL Gamecenter Live. What prompted me to do all this work in the first
26 place was the fact that the onboard Intel GPU couldn't quite keep up to
27 a live hockey game in fullscreen mode. There was occasional stuttering
28 of the video. I went to all this trouble in hopes of a better viewing
29 experience. BTW, I have 2 Dell Dimension 530's. On the one with only
30 the onboard GPU, glxgears shows just over 60 fps. On the one with the
31 ATI card it's jumped to over 262 fps.

33 Last minute note. DRM is *NOT* in effect. I'll be starting a
34 separate thread on that. It's "an excellent adventure" in its own right.
