John,
Immediately do a "dd" of your disk to a backup drive or tape.  Real
World Linux Security has some notes about this.  You can recover a most
of your data from that file.  Bob Toxen might be able to help you with
this.  He recovered lost logs from when we were hacked after the machine
had run for quite awhile under the cracker's control.  We got some
pertinent info from what we recovered.  Unless you have formatted the
drive and actually written over the part of the disk where /var was,
there is a good chance you can recover that stuff.  Email Bob at
bob at cavu.com for some advice.  I know how you feel right now, believe
me.  I hope you can get what you need back.  Just don't jump the gun and
assume it is all gone.  Make that dd copy right now.  You can work with
that later.  If you need some help with the backup and have SCSI-2
interfaces then I could help you if you want to bring the machine here
to KSU.  Example dd command:

dd if=/dev/hda of=/dev/hdb

I am sure there is some blocking factor issues if you go to tape.
