Yes, Steve, there is a work-around.

The problem is that DOS only allows 128 chars on the commmand line.
The solution is to abbreviate individual paths so that a large number
can fit in 128 chars.  Suppose, for brevity's sake, that you want to
include only two individual paths in the PATH environment variable:

subst f: c:\program\dos
subst g: c:\program\win386

path=f:;g:;

You have to tell DOS to allocate space for these "device handles" (f,g),
by including lastdrive=[letter] e.g.  

lastdrive=z

in config.sys.  Note that 26 (a-z) drive handles is all you get.

This is something of a bastardization of the SUBST command.
IBM/Microsoft introduced SUBST with hard drives.  It was designed to
fool older applications that were not hard disk aware.  So, if your copy
of PeachTree G/L looked for data on drive B:, DOS could fool it into
looking in a particular directory on the hard drive instead:    

subst b: c:\data\peach
