hi,
The following patch makes the chainloaded
uboot( http://al.robotfuzz.com/~al/maemo/u-boot/ ) load a 2.6.28 kernel
built with openembedded(and converted to uImage manually using the
u-boot for n900 website howto)

put the cover back to be able to boot.
(I sent that to the mailing list because mrmoku is sleeping, and he had
some difficulties to get it working)
