I thought I'd been assured grub2 worked fine for our 32 and 64 bit
platforms? :/.

The correct question here is why doesn't grub2 work on 32 bit platforms?

The answer might be "we need for time than is available in the 1.1
release to fix it" but I'd at least like to see the answer to the
question before we start with workarounds.

Cheers,
