Probably an interrupt handler is hanging.
Set up a serial console or netconsole or debug via FireWire.
Or simply switch to a text console (IOW to a VGA console or framebuffer
console, not an X11 terminal) and let klogd log directly to it. This may
give you at least parts of the last messages. I think it goes like this:
# killall klogd
# klogd
# modprobe yourmodule
