| Hey, thanks Bob.  I don't know if this helped Michael, but it sure

I won't know if this helped me just yet.  I haven't had the time to fool
around with it, as some crazy things have been going on with work.
*shrugs*.

When I do know, I will throw it up here.

And just out of curiosity:  Environment variables are all set
independant of the kernel, aren't they?

And just FYI as well, the behavior is 100% reproducable if you install
Slackware 10.1 which installs with a 2.4.29 kernel, and then compile a
2.6 kernel (to date I've only tried 2.6.11.x kernels).
