Here's the decode with it loaded.  The oops happens during the 
initialisation of ehci-hcd (from an init=/bin/bash clean system, I did 
modprobe usb-uhci then modprobe ehci-hcd and it oopsed).

Well this BIOS does insist I have 'sourth' bridge, so I don't have high 
hopes on that score :)

ksymoops 2.4.9 on x86_64 2.4.23-pre6-amd64.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.23-pre6-amd64/ (default)
     -m /boot/System.map-2.4.23-pre6-amd64 (default)
     -t elf64-x86-64 -a x86-64

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.
