That 'chainloader' didn't work at all: It seems GRUB2 here isn't 
understanding the HFS+(journaled) filesystem at all.  Neither in EFI nor 
BIOS grub2 can I see anything on that partition, even though I have 
module hfsplus loaded (I think - but lsmod in grub takes up more than 
the whole screen, so I can't see them all - is there any way to get 
around that?).

Also I decided to play around and try a few other commands in grub2.
cpuid (efi or pc) -- finishes instantly without outputting anything
lspci (efi) -- hangs (but it works properly in pc)
reboot (efi) -- hangs (but it works properly in pc)

yes it is similar (and I'd probably try and use the Ubuntu development 
branch for the next release, "intrepid") : however, what bothers me is 
that this seems to make the whole apt repo, not just the part I want, be 
a first-class citizen; so that if it contains a newer version number of 
any package on my system, it will install that if I ask to install the 
package, or it will offer to upgrade to that version if it's already 
installed (so I can't even begin to pick out which are the Ubuntu-stable 
updates).  I hope I'm missing some option that lets me avoid this risky 
nuisance, while still keeping tabs on the unstable linux-image packages?
