With kernel 2.6.32
1) booting 2.6.32 kernel on uSD
http://build.shr-project.org/tests/mrmoku/2.6.32/images/om-gta02/
download uImage to /boot
download modules and untar it to /
update uImage link in /boot
2) flash image
flash_eraseall /dev/mtd6
nandwrite -p /dev/mtd6 shr-full-eglibc-ipk--20100105-om-gta02.rootfs.ubi
3) then test if it works
ubiattach /dev/ubi_ctrl -O 2048 -m 6
mount -t ubifs ubi0:om-gta02-rootfs /media/om
ls /media/om
4) update Qi with dfu-util
http://build.shr-project.org/shr-unstable/images/om-gta02/
qi-s3c* expects jffs2 as rootfs
qi-ubi-s3c* expects ubifs as rootfs (with rootfs name om-gta02-rootfs which corresponds to name in ubinized image)
it is now in OE repository as qi_git.bb and qi-ubi_git.bb.
5) flash 2.6.32 also to NAND
6) boot it, test it, play with it

Performance
How to test: Please run 'bonnie\+\+ -u 0:0 -s 32 -m 16 -r 16' on a fresh filesystem. bonnie++ is now in shr-unstable feeds.
UBIFS
max_posedon provided some bonnie++ results using kernel 2.6.29

Status
11.1.2010
There are some issues for now, because kernel 2.6.32 isn't really ready yet: GSM doesn't work WSOD (White screen of death) could/will come up..
It's also possible to start and use the system with the last shr-kernel, but theres the ubifs-module unstable (but gsm works, wsod not seen there)
