If it got as far as starting cron, then the problem isn't the kernel.
All that's left in rc2.d after cron is fetchmail, removing nologin, and
stopping the boot log.
Unfortunaly, you can't boot into single or init=/bin/sh from ssh (you
need a serial console) which is what I usually do after a kernel
upgrade, just to be sure.
When you say it hangs, does it kernel-panic? If so, you can tell the
kernel to reboot after a delay instead of just sitting there.
