Possible to remove MBP Software Update 1.3?

HI all,

Long story short: Bought a new i7 MBP, moved the HD from my previous gen MBP to it, installed MBP Software Update 1.3, decided I didn't like/need the new MBP, got refund, put HD back in old MBP.

The problem: MBP Software Update 1.3 is only meant for the 2010 models, so I'm wondering if there's any way to uninstall it, now that the HD is back in my 2009 MBP. I'm getting a few 'can't repair permission X' messages on Disk Utility and although I've not had any actual problems, for peace of mind I'd like to roll back. I can nuke the problem with Time Machine, I guess, but I'd rather avoid that if at all possible, just cos of Time Machine's potential to fail.

Anyone got any thoughts?

Cheers!

Gah - Time Machine it is, then.

Wish me luck...
