+Where did the power3/power4 ppc64 flavours go ?
+===============================================
+
+As of 2.6.12, and anticipating the inclusion of a powerpc biarch
+toolchain in debian sid and then etch, we have dropped the 32bit 
+ppc64 flavours. I will provide unofficial -pseries (replace all
+previous 64bit flavours) at :
+
+  http://people.debian.org/~luther/ppc64
+
+until we are able to build them inside of debian, which will
+hopefully be only a couple of weeks now.
+
+But if you feel impatient, here are the instructions on how to build 
+those arches yourselves :
+
+  1) install the ubuntu/breezy glibc and gcc-4.0 packages (preferably
+     in a sid chroot)
+  2) go into debian/arch/powerpc
+  3) rename the 32bit flavours to noconfig.powerpc[-smp]
+  4) rename the 64bit flavours to config.pseries
+  5) edit Makefile.inc, and change the last three lines to :
+	headers_subarch = powerpc
+	build_subarch = powerpc64
+	default_config = pseries
+  6) go into the toplevel, and launch :
+	dpkg-buildpackage -rfakeroot -us -uc -B
+
+This should build you a couple of packages, where you would be interested
+in the linux-image-2.6.12-1-pseries and linux-headers-2.6.12-1-pseries ones.
+
+Enjoy,
+
