I'm pretty sure your out of luck - VM doesn't support mh or maildir folders
as far as I know.

If your  running on a 32 bit machine, I think your out of luck. You cannot
increase the maximum buffer size. Under Emacs, I *think* you are limited to
a maximum integer you can represent with 28 bits. If your on a 64 bit
system, its the maximum you can represent with 62 bits. 

Note that there is a difference between emacs and XEmacs. I believe XEmacs
has the ability to represent 31 bit integers using some trickery with tag
bits.  

The best suggestion I have is to use some other editor to open your mail
file and split it into two files at a sensible position (i.e. between
messages. You should then be able to open these files with VM and sort them
into smaller folders. I'd suggest using something like procmail to split
your download - maybe use fetchmail/getmail to retrieve the mail and split
it  into different folders. 

Of course, if you have access to a 64 bit machine, you could move your
folder there, run a 64 bit verion of emacs and split things how you want,
move it back and your done - a hassle, but a solution none th eless.
