I fixed this problem by booting with a grub 2 disk. I changed the grub 2
command line to vga=normal.
I removed quiet and splash to skip the unviewable boot splash.
This allows the garbled characters to be seen.
I have an hvr-1600 card in the box so I guess it is still subject to the boot
hangup bug.
Added the vmalloc=256M to the boot params and that fixes the hang up.
Additionally I made an Xorg.conf to run the vesa driver and used that to get
fully booted.
I fiddled with reinstalling the nvidia driver. I think the previous steps
actually render using the vesa driver
superfluous.
All this must be done from the command line by selecting single user from the
options presented when booting via grub 2
cdrom.
So I think the problem must be the boot splash is set to some video mode the
nvidia card does not like. Plus I had
one more old bug that hung up the boot process.
