Yes, your kernel would become a supported kernel at ATrpms which means
that all flavour/arch combinations for ia32 and x86_64 would be
supported by the kmlds at ATrpms, too.

Yes, that's the way to go. Some things can't be build externally, then
we need to supply a different kernel and also all kmdl that go along
with it. ATrpms had such kernels for 2.4 including openswan/xfs/v4l2
etc that could not be built separately. For recent FC released kernels
there haven't been many projects that cannot be built externally and
that would be of general interest to justify respinning kernel
packages. swsusp is one of them.

Best thing would be at ATrpms, and even by the buildsystem there.

Even if there are bugs, it would be nice to habe x86_64 and smp, so
people can test and report to swsusp upstream.

How about the following model:
o Development of the packages happen on your box
o When you are happy to release a kernel package you upload the
src.rpm to the ATrpms build server via rsync+ssh.
o You let the buildserver generate kernels for i386/x86_64 on all
flavours (including smp and xen) and all subarchs, as well as all
o Packages get automatically into ATrpms' repo that way, and are
available for apt/yum/smart etc.
The packages would have to be labeled testing or even experimental at
first, so noone gets burned. Slowly we can increase the stability
level as we get more confident with the user feedback (or not, if it
is negative, of course).
When all goes well, you will get a few envy people from the RHEL4 camp
asking you to weave swsusp into RHEL4 kernels, too. :)
