Software to remember PRAM settings?(Mouse speed particularly)

[Torbar]

I don't like keeping batteries in my compact Macs due to the potential to leak(plus I have like, 10 of them, and that's alot of batteries), but I've noticed the mouse speed doesn't stay between reboots, so I imagine it's a PRAM setting.  Is there any software or extension or whatever that will keep the mouse speed setting between reboots?  Not sure what other settings are stored in PRAM(besides date/time, which I don't care much about keeping).

The version of TechTool I have can save and restore PRAM to and from a file saved on the disk.
