An API change shouldn't be necessary.  The plan to support large sends was to 
change how the void *mad pointer in struct ib_mad_send_bug is used.  Currently, 
it references a single data buffer.  The fix is to have it reference a list of 
buffers for large transfers.  See:

http://openib.org/pipermail/openib-general/2005-October/012723.html

for more details.

And yes, a patch for this would be great.  Otherwise, I will eventually get to 
this, but it may be a few weeks before it bumps up high enough on my priority list.
