Apologies if I did this wrong, but I get an oops on startup now. Oddly,
2.5.46 used to work for me, ...
Here's what happened when I ran it through ksymoops (let me know if I did
anything wrong or you need more info?)
ksymoops 2.4.6 on i686 2.4.19. Options used
-V (specified)
-K (specified)

-O (specified)
-m /boot/System.map-2.5.46 (specified)

I also got this once, but wasn't able to reproduce it.
