I have *no* software raid that I know of!  Yes /var does have its own 
partition.

I can boot off the USB stick with Lucid 10.04 LTS on it, but I did not 
install from it.  This was a distribution upgrade using Update Manager.

The kernels shown by GRUB are

2.6.32.21
2.6.31.21
2.6.27.11

I can't boot from the first two.  The last one boots to a log in prompt, 
then freezes, but gives me a console session on tty1.  It also boots in 
recovery mode.
