You can try to do (on Xen) 'console=vga  vga=text-80x50 guest_loglvl=all loglvl=all 
and on the Linux command line: "console=hvc0 earlyprintk=xen loglevel=8 debug 
radeon.modeset=0 radeon.modeset=0"

That should give you some idea where it is crashing and take a photo.

If you are capturing logging with a photo, it can be helpful to add a boot_delay parameter eg. boot_delay=100 to the kernel line, particularly if the interesting lines scroll off the top of the screen before you can capture them. It does slow the boot down considerably though so you may need to adjust the parameter to get the balance right between it being slow enough to capture without taking ages to get to the crash.
