Going through dmesg here on the boards I've got (not the same as yours,
so there may be differences, but this part of the boot process should be
pretty universal), I get this...

Freeing initrd memory: 158k freed
VFS: Mounted root (ext2 filesystem).
Journalled Block Device driver loaded
kjournald starting.  Commit interval 5 seconds
EXT3-fs: mounted filesystem with ordered data mode.
Freeing unused kernel memory: 120k freed
usb.c: registered new driver usbdevfs
usb.c: registered new driver hub
usb-uhci.c: $Revision: 1.275 $ time 08:32:07 Dec  1 2003
usb-uhci.c: High bandwidth mode enabled
usb-uhci.c: USB UHCI at I/O 0xd400, IRQ 5
usb-uhci.c: Detected 2 ports

Perhaps its the usb subsystem that's not being initialized quite right?
Try turning it off in the bios if it's not required for what you're
doing.  That may help in troubleshooting the problem.

You may want to look at /var/log/boot.log and dmesg to try to figure out
what's happening (or not happening as the case may be).

I know I've found a couple oddities with these boards (some of the
hardware is just that little tiny bit off of standard which made for
some head scratching), but for the most part, they work quite nicely and
as advertised.

------------------

No joy, there are no options to disable USB and as I pointed out before 
nothing is written to the logs (boot.log or messages) during any of the 
boots.

I added some traces to rc.sysinit, none of these appear.

I agree that given the location of the hang then USB seems to be the 
error...

I was able to boot up the Fedora CDs and run through the upgrade process 
on the new motherboard, but it still doesn't get past the same message.

I'll try building a kernel with no usb support and see how I get on with 
that.
