ati_drv.o & fonts in XFree86-4.1

First of all, I'm not a developer. But I guess someone
might be interested in this problem. If this is not
appropriate in this list, please ignore.
Anyway, I compiled and installed XFree86-4.1 on my iMac revB
(Mach64, kernel 2.4.6-pre1, gcc-2.95.3 & glibc-2.2).
Actually, I applied XFree86-188.8.131.52-latin2.patch from
Fukui-san's src.rpm. After the installation, X became much
faster with new ati_drv.o. x11perf --scroll500 showed
118.0/sec on 24 depth. In contrast, it had showed 54/sec on
XFree86-4.0.2 (actually, I had used ati_drv.o which Ani
Joshi had hacked for xf-4.0.1 because it's faster than that of
However, all fonts including Japanese fonts in windows
looked very ugly. Actually, they were reversed and/or too
condensed, so they could not even be read. This happened on
almost all software like xterm, Eterm, kterm, XEmacs,
netscape, etc. However, fonts looked normal when I used
tkdesk to open and read files. It's very weird.
When I deleted ati module and used fbdev module in
XF86Config, all fonts returned to normal appearance.
However, x11perf --scroll500 demonstrated 11-12/sec. This
speed is only one-tenth compared with the speed with ati.
I exchaged ati_drv.o of xf-4.1 for ati_drv.o which Ani Joshi
hacked for xf-4.0.1 and deleted fbdev and added ati in
XF86Config. Then, all fonts in X looked normal. x11perf
--scroll500 showed 54/sec again. Therefore, I guess
ati_drv.o of xf-4.1 is the cause of this font weirdness.
Does someone have any idea about working around this
problem? I really want to use the new ati driver because
it's much faster.
Thanks a lot in advance.
