Ok I've got Fedora 12 to work with multiboot and it's indeed alot faster than I expected.
I've installed the kernel packages from MohammedAG at: http://mohammadag.xceleo.org/public/...s/framebuffer/
And I'm using his: http://mohammadag.xceleo.org/public/...e-fb-omap1.bin as /boot/multiboot/vmlinuz-2.6.28-framebuffer1

However I've got a few problems.
First of all the sound doesn't work, there is no documentation on that.
Second problem is that the mac-address changes on each boot, deleting the 70-persistant-net-rules is not really an option since my dhcp server will still assign a different ip-address. I would like to make the mac address to stay the same.
And the last problem is that I can't find the n900-support script for the battery.
Any ideas?
