I can confirm that various operations are much speedier now, including booting my Debian. This is quite awesome. What is not as awesome that distributions etc. never questioned especially the debug features being enabled :) But that's understandable of course given how much stuff there is generally that only one person is actively dealing with etc. Could someone with access rights disable debug and pre-empt features in gta02_moredrivers_defconfig in git.openmoko.org? I think wrong stuff there leads to the information not spreading widely enough. -Timo
