Nice. Mine took 20 mins longer (real time), of which there was 3 mins
more user time. I had some other processes running, so... I was a bit
worried about the size of the deb, only 8.5M whereas my x86 debs are all
20+M, probably due to a lot more drivers.
I also cross-compiled the kernel on a x86 laptop (1.5 GHz) and that took
me about half an hour. First, I though that it wasn't working right (I
noticed the 8.5M) but maybe it was. I used debootstrap on ubuntu edgy,
chrooted into it, added the emdebian sources and installed the cross-gcc
for arm. I used make-kpkg with --arch arm and --cross-compile
arm-linux-gnu. You see, I didn't document it, :-/ Anyway, I'm going to
test both kernels to see if they work. If they do, I really like
cross-compiling even though my x86 compiled kernel was a tiny bit larger
in size. Maybe not exactly the same compiler/linker/etc. used?
