Wow, thank you!  That is a big relief.

I don't mind asking RH to statically link the modules if there is good
reason.  However I don't understand why it is needed.  512M is a lot
of memory!  How can it be filled to the extent that the blkbk/netbk
modules won't load?  What are their requirements?

It is possible that knowing the dom0_mem=1G workaround will be enough
until Tristan's xencomm work is finished (I think he's almost done)

Thanks again,
Aron
