You can keep both kernels and just use the bootloader to select which one to
boot into. So if your new kernel doesn't work just reboot and use your old

Yes, but this means recompiling all external modules (nvidia, madwifi)
every time I boot in a new kernel if I want them to work, isn't it?
No. Kernel modules are kept in /lib/modules/VERSION/ meaning you will
have the older ones working when you boot the older kernel again.
