I once used a printk in the keyboard irq handler to check a nonstandard keyboard. You may put a printk() in the timer interrupt handler. That should show that the irq handler works. Of course you don't want to run such a log-filler for long... :-)
Maybe you can get the machine to boot by skipping the bogomips calculation completely - by hardcoding the value your machine used to come up with? Not for production use - just to get a debugging kernel going.
