Other programs also starting faster.
But on the video I ran libreoffice before so n900 loaded it from ram - with reseted swap libreoffice starting in ~17seconds.

I will make video with other programs after reseted swap

Quick guide: (it's my way to do it, you can do it by several other ways)
1) Install bootmenu on n900 - now you can access all emmc 32GB flash (not only 27GB vfat partition)
2) Reboot n900 with open keyboard and choose usb connection
3) Resize 27GB fat partition and create new partition >3.2GB
4) Copy content of image to partition by dd tool (you can do it on n900 or PC)
by example: 5) Change chroot config by editing /home/user/.chroot - remove # from #IMGFILE=/dev/mmcblk0p4
6) It's working
7) You can convert ext3 partition to ext4 by terminal (in this case you must have power kernel, but I think everyone have it)
Type in xterminal on n900
