Late 2006 MacBook Pro replacement keyboard: firmware update required?

Question

My late-2006 2.33GhZ MacBook Pro is still going strong -- except that a group of keys on the internal keyboard stopped working two weeks ago, requiring me to replace it. It was a delicate operation, but it worked like a charm.
Shortly thereafter, though, I started noticing a symptom that jogged my memory: when I'd go to type something, quite often the first character would be dropped, as if the keyboard wasn't waking from its low-power state quickly enough. This had been a common complaint with this model, and Apple addressed it with the MacBook Pro Keyboard Firmware Update released in 2008. I recall installing it and very specifically noticing the problem had vanished.
So of course now I'm wondering: is it possible my new keyboard needs the firmware update too? You can see the catch-22 I'm in: I can't install it, since the computer is convinced the updater has already been run. when I do run it, I get a generic message that the update isn't necessary. I even tried removing:
/Library/Receipts/boms/com.apple.pkg.BuiltInKybdFirmwareUpdate.bom
to see if that would enable the updater to run, but no dice.
Of course it's possible I'm simply losing my mind, and the keyboard already has the update. Could someone else with this exact model -- someone who has run the keyboard firmware update -- tell me what version their internal keyboard is at, based on:
System Profiler -> Hardware -> USB -> Apple Internal Keyboard
Many thanks!

Hi Eric,
Any resolution to this? I do not have the exact same MacBook - mine is a 17" MacBook Pro, but in case it helps you, my updated keyboard version is 0.18 using the same installer
My problem is that when I originally used that software update (over a year ago), it created an intermittent keyboard/trackpad failure. Every 2 days, on a very regular basis, my trackpad and keyboard fail. In order to fix the problem, I go to the Utilities folder and run the "Built-In Keyboard Update Firmware" that the original DMG installer installed there. Once I run that program I'm good for another 2 days. Apple, of course, has no clue to what's going on.
Why am I telling you all this? I noticed that you are running Snow Leopard. I tried to upgrade to Snow Leopard a couple of weeks ago. After the Snow Leopard install, my keyboard failed like clockwork; however, it turns out that the firmware installer that I have been relying on for the last year to fix my intermittent failures no longer works under Snow Leopard. My phone calls to Apple were a complete waste of time (apparently there is a very low threshold to get on the "Genius Bar"). One of my questions to them was specifically about a way to re-run the installer from the DMG file. They again had no clue, and In the end I had to downgrade to Leopard to get my Keyboard back.
All that said to let you know that even if you can find a way to re-install the firmware updater (I'd like to know how, if you figure it out), there is a good chance the actual firmware update won't install under Snow Leopard.
Good luck - let me know how you make out.
