This is strange. I'm using a 2.8 MB image to boot up my internet router,
and it works without a problem... So it doesn't seem to be a general
problem.

How about a different network card? What type if TFTP server do you use?
Does the server print anything in the logs? You should also check the
TFTP traffic using tcpdump or ethereal. Does the client send out a request
for block 1038, but doesn't get a response from the server?
