Hello Pavel,
here are some hints for booting 3.8+ kernel on n900:
"multiboot" package from Maemo Extras is horrible hack which can
be used only for booting maemo 2.6.28 kernel. it flashing new
kernel to n900 nand, then reboot device, start maemo init and
mount/chroot into new os dir... after reboot it erasing kernel
nand area where is normaly uboot placed, so do not install it!
uboot in Maemo Extras cannot boot 3.x kernels because autobuilder
(Extras server app for buidling packages) has very old gcc which
produced semi-(non)working uboot (can boot some 2.6 kernels).
my uboot builds compiled by gcc 4.7 (which can boot 3.8 kernel):
http://atrey.karlin.mff.cuni.cz/~pali/u-boot/
info thread about uboot on n900:
http://talk.maemo.org/showthread.php?t=81613
kernel git repository with n900 patches (now based on v3.8-rc3):
https://gitorious.org/linux-n900/linux-n900
open source flasher 0xFFFF (working on x86-64 too) which can load
kernel and initfs via usb to n900 RAM without flashing nand:
https://gitorious.org/0xffff/0xffff
rescueOS - minimalistic n900 initrams distribution with usb mass
storage (eMMC and SD) and usb cdc ether for telnet console
http://206.253.166.96/N900/rescueOS/
If you need help with booting some upstream kernel on n900 join
to freenode #maemo-alternatives channel :-)
