What driver? And what version number?

A few possible issues:
Endian correction (unlikely, if a few packets are getting through)
Burst length problems (although I don't know of any specific Sparc bugs)
A problem with the ring wrap (we need to know the driver version).
This could be interacting with the DMA-able page allocation on the Sparc
