I needed to recompile xen first with debug flag set. Now I get 
results from earlyprintk.
Please find attached:
xl_dmesg_512:  domU (32bit) booting fine with memory = 512
xl_dmesg_2048: domU (32bit) silently crashing with memory = 2048
Both tests with your patch active and no other changes in between.

Log shows
BUG: unable to handle kernel NULL pointer dereference at   (null)
and oopses out.

xl list does not show the process. ps shows that the corresponding 
qemu-system-i386 process is still alive and has to be killed manually.
Thanks for working on this and enjoy your weekend,
Christian
