I gave it a bunch more memory and now it hangs try to boot at the same
point as before...

<Boot Process>
RAMDISK driver initialized: 16 RAM disks of 16384K size 1024 blocksize
loop: loaded (max 8 devices)
Xen virtual console successfully installed as xvc0
Event-channel device installed.
netfront: Initialising virtual ethernet driver.
xen-vbd: registered block device major 3

Something in the way PV GRUB is doing things, since booting manually
with kernel and ramdisk still works.

It may be some option to the kernel command line, i tried adding:

things like the following to kernel grubdom line, with no luck, still hangs.
xencons=tty root=/dev/hda2
console=tty1 root=/dev/hda2
console=xvc0 root=/dev/hda2

The bigger problem though is the PV GRUB isn't actually working like I
might expect it to.

Do I need to pass the menu.lst file in the ramdisk option to see a grub
menu? Or should it detect the menu.lst within the guest disk image file?

Is there a simple example that I could download and work with to get
a sense of a working PV GRUB example?
