Currently in OpenSolaris, but not yet backported to S10, is a daemon called intrd which monitors interrupt usage and redistributes interrupts to even out the load. It's not an observability tool, admittedly (that's /usr/sbin/intrstat), however it does its work based upon kstats:
$ kstat pci_intrs::: These kstats are private to intrd, so I wouldn't start writing enduring scripts that assume these kstats are set in stone, as you will be disappointed down the road when something changes. And they are limited to interrupts from pci devices. But it will tell you the exact amount of time (in nsec) used by the interrupt.
