Yes, indeed, the patch is available and I now have it.
This patch can be obtained from Sun (for no charge, from what I am told).
I have also made it available via anonymous ftp on procyon.cis.ksu.edu,
(in pub/sunfixes/le0_patch.tar.Z) for those blessed with Internet TCP/IP
access.
Many thanks for all those who responded:

Here's an extract from the README:
This patch contains a slightly modified 4.0.3[c] lance ethernet
driver (if_le.c) and object files for sun3x (hydra), sun4 (stingray),
and sun4c (SPARCstation1) as an effective patch for 4.0.3[c] lance
xmit memory underflow ("transmission stopped").
1. Increase LANCE_MIN_TU from 100 to 102, this effectively
eliminates UFLO (!)
2. Minimize leintr lance slave register accesses -
this is also a factor in UFLO.
3. Never print "Transmission stopped" or "memory underflow"
error messages.
This patch also fixes the panic: le0: RINT: Buffer owned by chip
problem.
