I totally forgot about this one:
To summarize what _my_ problem was...
I found out that the slowdowns were only affecting 32bit application (which
includes everything pushed through wine) and also ut2003, which I used for
testing. ioquake3 was compiled for 64bit (and it wasn't affected).
I probably never had any direct HW-accelerated rendering for 32bit applications
in the first place, but I didn't notice this because the indirect rendering
(which was selected by default, don't ask me why) wasn't that slow. Now it was
either an update to mesa or the mesa gentoo ebuild that "fixed" a problem, so
that NOW the sw rasterizer was now loaded by default (I looked like that
loading of the 32bit swrast failed in the past, resulting in indirect GLX). Of
course this resulted in awfully slow rendering.
After creating custom libdrm and mesa libs in /usr/local/lib32/ and also doing
a check with 32bit glxinfo the whole rendering is now HW-accelerated, slowdowns
are gone for good :)
