uname -a on my previous kernel gives:
NetBSD 1.5.2 NetBSD 1.5.2 (GENERIC_LAPTOP) #3: Sat Aug 18 23:43:41 CEST 2001
he@hamster.urc.uninett.no:/usr/src/sys/arch/i386/compile/GENERIC_LAPTOP i386. The machine is a Toshiba Sattelite 1800 s253
>Description:
Just tried to upgrade from 1.5 to 1.6.2 on my laptop. Installation went OK, but I can't boot the machine anymore. When booting, I get a page fault.

I copied this from the screen:
NetBSD 1.6.2 (GENERIC) #0 : Tue Feb 10 21:53:10 UTC 2004
(but I tried GENERIC-LAPTOP and GENERIC-DIAGNOSTIC as well)
