To install the 2.6.xx.x uImage to /dev/mtdblock1(nand), you cannot do that by press f1+fn+left shift, this will mess up because the /dev/mtd0 bootloader is not made for 2.6 kernels.
There are several way's to do/fix that
1) If you want kernel 2.6.xx.x to be installed on nand
use an uImage 2.6.xx.x copy to fat16 sdcard partition
First try-out with fn+left shift if it boots ok.
Next is to copy uImage to the /dev/mtdblock1. Start an terminal and type cat uImage > /dev/mtdblock1
2) If you want to fix/restore older 2.4 kernels.
Copy the existing 2.4 kernel (such as the one from elonex, skytone, alpha400) to fat16 sdcard partition.
First try-out fn+left shift if it boots ok.
Restart and Press f1+fn+left shift and this will copy the 2.4 uImage correctly to /dev/mtdblock1
3) For development/new package installations it is safer to boot a distro from SD card, especially if the size will be close to 1GB.
The 184.108.40.206RV kernel is not able to boot an distro from SD card, it can only boot from nand, limited space on nand (1G).
This one is able to boot from SD card by keep Fn pressed.
4) default boot the kernel from SD card, can be done for 220.127.116.11 kernel by changing the kernel sources
(arch/mips/jz4730/board-minipc.c default from /dev/mtdblock4 to /dev/mmcblk0p2) and recompile.
This is not necessary when using one of the above three options.
If you still want that, I can recompile the 18.104.22.168 version and put it on kwaak.
