I have a similar vintage machine to yours (366MHz iBook SE)
also with a
GMAC card, but running release 3.1.  I just transferred a
400MB file as
a test, and didn't encounter this problem.  Could this be a
regression?

Hmm, gem always worked fine on my iBook G4 ( 800MHz model )
Please post dmesg and the gem's pcictl dump output, both of
you.

It may very well be.  I transferred the file to this system
when it was
running NetBSD 3.
