IF you got a kernel panic, then you may need more than a time machine backup. I would be inclined to run Disk Utility verify disk (and repair disk from Disk Utility on the installer DVD if verify disk showed problems) then I would download and reinstall the 10.6.2 combo update. It can be gotten at http://support.apple.com/kb/DL959
If Mail still crashes on launch after that, maybe try reinstalling Mail from the "optional installs" package that is on the installer DVD -- you can pick onesey-twosey from a select list of OEM applications, that includes Mail, to reinstall.
In either event, I would run software update after a combo update and/or mail reinstall to make sure everything is back up to the latest and greatest. Lastly, maybe a "rebuild mailbox."
