It's not the machine. It's GRUB not being able to boot from ext4.

Right now there's not a stable version of grub that supports booting a
kernel from a ext4 partition. It's recommended that you keep /boot in a
ext3 partition.

Preliminary ext4 support seems to have been added
<http://svn.savannah.gnu.org/viewvc?view=rev&root=grub&revision=1699> to
the 1.97 version of the GRUB2 development branch.

There's also a Google Summer of Code project
<http://code.google.com/soc/2008/suse/appinfo.html?csaid=91DC4C762E7EE6D7>
(from opensuse) which seem to have developed
<http://code.google.com/p/grub4ext4/> ext4 grub support. Both projects
-GRUB2 and the GSoC projects- seem (sadly) to be different efforts.

The grub package in Ubuntu 9.04 and later includes a patch to support
booting from ext4 filesystems (see bug 314350
<https://bugs.edge.launchpad.net/bugs/314350>)
