It would be great if anyone with device would care to update http://wiki.maemo.org/Nokia_World_2009_QA#Maemo_5 (the 'output of' part)
Heck, I would love to get N900 firmware image, that would answer me a lot of questions :-)

dmesg would be best done early after boot (like adding dmesg >/dmesg.txt to /etc/init.d/rcS or similar early boot script), there is one here http://talk.maemo.org/showthread.php...952#post343952 done by hand after device boots. With the boot script we could get a few more lines but it is nothing critical.
As for swapping to internal flash... I'm not sure why the current flash partition size is 768MB (maybe because of wear leveling?) but maybe 256MB only should do too. And while mtd is not a block device so one cannot swap to it direcly, there appears to be one old attempt of mtdswap driver done/paid by Nokia
http://www.infradead.org/pipermail/l...ch/017603.html and there are also attempts to implement block layer over UBI http://lists.infradead.org/pipermail...ay/021609.html so swapping to internal flash might be good idea when system is on MMC.

One thing which was suggested was putting swap on the fast, 256MB chip and the whole rootfs on the eMMC (32GB, partitioned into both VFAT and ext3).
Perfect would be to have two swap partitions first the fast small one with 256Mb and a secondary ~1Gb. Not doable (in practice) afaik, but a man can dream.

It does do "similar" to the N8x0s' linuxrc, but unlike linuxrc, it has an explicit clause saying that redistribution is forbidden.

But, instead of "$T2S -t "initfs version:" -s 2 -x $x -y $y -B $bg_color", we now have: "text2screen -t " no initfs \o/" -s 2 -x $x -y $y -B $bg_color"
