Comment 17 for bug 693671

This brings the assembly slightly more into line with GRUB's C code, and execution now reaches the end of wubildr.mbr. However, there's still no observable output from wubildr, so either the wrong code is being loaded by wubildr.mbr, the jump to wubildr is failing somehow, or something is failing early on in wubildr.

I'll see if I can insert a small amount of code into GRUB's startup sequence to narrow this down further.
