The support of this configuration is not yet mainline in the linux kernel. A patch from cvubrugier is under validation to be put mainline in the linux kernel. You can find it here

/dev/sda5	XFS             data
/dev/sda5	SWAP
/dev/sda6	RAW Kernel
/dev/sda7	ext3 		/
/dev/sda8	ext3
/dev/sda9	ext3 in unionfs
/dev/sda10	RAW Kernel 

The hard disk can be entirelly wipe. But if you want to be able to boot your new system without have to flash uboot you need to respect the position of the kernel and the root filesystem.

The kernel have to be on the /dev/sda6
The root filsystem have to be on the /dev/sda7

To install your custom build kernel do a raw paste on /dev/sda6

#dd if=uImage of=/dev/sda6

To install your system you can follow instruction for Debian or ArchLinux or even build your own system with buildroot.
