Kexec allows quickboot
Kexec is handy for a quick and "real" test of the latest initramfs or the latest installed kernel. Install kexec-tools and be quite picky about how you pass the cmdline args. Be careful to launch the last execute from console. Sync and unmounting discs before is recommended. ipw2200 panics since ever on kexec, simple unload brings it back to life. When using in combination with initrd/iniramfs uname > 2.6.15 is recommended.

kexec -l -t bzImage --command-line="ro root=/dev/sda1" \
--initrd="/boot/initrd.img-2.6.16-1-686" /boot/vmlinuz-2.6.16-1-686

kexec -e
