I can't seem to reproduce the changing behaviour outside of my distro's package
manager (gentoo's portage).

When using mesa-7.1, installed through portage, the corruptions are colorful.
When using mesa-7.2_rc, installed through portage, the corruptions are white.

I checked the configure options portage passes for mesa-7.1:
./configure --prefix=/usr --host=i686-pc-linux-gnu --mandir=/usr/share/man
--infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc
--localstatedir=/var/lib --with-driver=dri --disable-ttm-api --enable-glx-tls
--with-dri-drivers=,swrast,i810,i915,i965 --disable-asm --disable-glut
--without-demos --disable-xcb --disable-debug --disable-glw --disable-motif
--build=i686-pc-linux-gnu

The configure options string for mesa-7.2:
./configure --prefix=/usr --host=i686-pc-linux-gnu --mandir=/usr/share/man
--infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc
--localstatedir=/var/lib --with-driver=dri --disable-ttm-api --enable-glx-tls
--with-dri-drivers=,swrast,i810,i915,i965 --enable-asm --disable-glut
--without-demos --disable-xcb --disable-debug --disable-glw --disable-motif
--build=i686-pc-linux-gnu

The only (significant) difference I see there is the use of the asm
optimizations.

Furthermore I did this:
Compiled a fresh git clone (mesa-7.2 branch) with only passing the DRI drivers
list (swrast and i915, I don't need more) to configure.
That also produced white texture corruptions.

I recheck this, but as far as I can see the asm code seems to cause trouble...

Greets,
Tobias
