Ok, after building we have:
root at scorpion:~# uname -a        
FreeBSD scorpion.sorbs.net 5.3-RELEASE-p9 FreeBSD 5.3-RELEASE-p9 #0: Tue 
Apr 26 14:35:20 EST 2005     
root at scorpion.sorbs.net:/usr/obj/usr/src/sys/SCORPION  i386

(why not #1..?)  the build date is current, the config file is at: 
http://scorpion.sorbs.net/SMP/SCORPION

dmesg from boot -v is at: http://scorpion.sorbs.net/SMP/dmesg-v.txt

acpidump -t -d is at: http://scorpion.sorbs.net/SMP/acpidump-t-d.txt

sysclt -a is at: http://scorpion.sorbs.net/SMP/sysctl-a.txt

Have I forgotten anything? (I haven't done a non-acpi boot from this new 
kernel)
