Hello, Jerome.

As you've noted earlier in the message, swsusp will be helpful, I think.
Here's my suggestion.

1. setup swsusp/swsusp2 on target machines (swsusp2 works pretty well)
2. setup small (10G maybe) test partition on target machines with
minimal distribution (just install on one machine and copy the partition
over)
3. setup netboot for target machines (reserve one machine for kernel
serving)

When a new kernel comes out...

1. build the kernel and set it up for netbooting
2. software suspend testing machines & reboot'em with the new kernel
using netbooting
3. see whether things work
4. reboot and resume production system

The suspend/resume instead of full rebooting should save a lot of time.
If you also use netbooting for the production kernel, you can just
change settings on the kernel serving machine to select which kernel to
boot and which partition to mount for root fs.
