Yeah, I thought it odd. And now thinking back, I originally could use
a compressed kernel so either grub or the xen kernel changed in some way.
I was pretty sure it was after a xen update (kernel file size?).
Honestly, it's been a non-issue.

I'd say this is probably half my problem. I normally have a small root
partition but of late have got out of the habit. With xen, I've not
bothered at all but as I said above, pretty sure it was working with
a stock install at the beginning and I haven't altered the disk layout.
I might have a look at the original xen3 kernel, check the size and see
if it has the same limitation booting. It's not a problem for me at all
but it might be worth knowing why so it can be documented.
