If you remove the 'vga=XXX' option on the kernel command line it works, this doesn't happen.

@Holger: Does it help if you boot with vga=0 ?
is this a duplicate of https://bugzilla.novell.com/show_bug.cgi?id=688714 ? i also had a hanging modprobe and migration process on the 11.4 -default kernel
Yes, it is. *** This bug has been marked as a duplicate of bug 688714 ***
No, it does not help to boor with vga=0 - same problems with this option.
Could you please follow up in bug #688714 ?
