Panic on boot

[Donn Miller]

I've been getting similar panics for the past 2 weeks or so on my HP 
Pavilion laptop (N5440, 850 MHz Pentium III).  Sometimes when I attempt 
to boot, like 1 out of 20 times, it doesn't panic for some reason.  But 
I do get the same results with every panic, so I know it's not a 
hardware problem.  These occur after "vga0" is probed.  It's an S3 
Savage chipset.
