A very busy day on LWE. Met some people to talk about the AlBooks of Apple when Mark Shuttleworth came up to the GNOME booth to talk about Ubuntu. I was talking about my XFS issues (should have been the perfect solution to address my problems) and that I'd like to have a Custom-Ubuntu-Kernel-HOWTO.
Had my talk about GNOME, I was quite happy with it as I didn't finish the talk and had almost half an hour of my time left :-). When taking back my hardware Debian's Alexander Wirth came up to me and told me that Ben Herrenschmidt released a test patch for suspend to ram (funny, haven't I been talking about a custom-kernel-howto for Ubuntu some hours before?).
Created a new custon kernel for my powerbook (which is still runnning Ubuntu). I used the standard Debian way of kernel compilation, removed the initrd stuff from yaboot.conf (this will break future Ubuntu kernels, but I don't care about them). At least suspend to ram works (including the "breathing" LED).
