The latest palo (PA-RISC Boot Loader) allows loading of a
gzip-compressed vmlinuz kernel. So let's switch to build a vmlinuz file
when we build a palo boot image.

PALO version 1.9 (or higher) is required for this which is available in
the dev_gzip branch of
git://git.kernel.org/pub/scm/linux/kernel/git/deller/palo.git

Helge, as the resident palo guru, could you update the debian/ 
changelog and
build a new package when you make changes?  We have gone through about
three versions without any documentation as to what was changed.

I have built a palo-1.19 package which should be uploaded to the  
archive soon.
Made up something for changelog.

Sure, that's what I had in mind. And add a spec file for RH :-)
But I just sent the patch to patchwork so that it's not being missed at some point.
I did not yet wanted to apply it....

Please don't upload it yet.
It still needs more testing.

Holding.

FYI, I've just uploaded a new palo-1.90 package with changelog and such to our repository at parisc-linux.org.
My palo source repository is http://git.kernel.org/cgit/linux/kernel/git/deller/palo.git
The master branch now holds all my changes - do not use the dev_gzip branch any longer.

I'm planning for a palo-2.0 package as soon as I have time to finish the other wishlist items (e.g. xz-support, loading ISO/tftboot images, ...).
