Which Etherboot driver are you using? There was a mod made some time ago
to a couple of the larger Etherboot drivers:
/* transmit descriptor and buffer */
static struct txdesc txd __attribute__ ((aligned(4)));
#ifndef USE_INTERNAL_BUFFER
#define txb ((char *)0x10000 - BUFLEN)
#else
static unsigned char txb[BUFLEN] __attribute__ ((aligned(4)));
#endif
What I am wondering is if txb at 0x10000 is incompatible with something
that grub is doing. I think the only drivers that do this are tulip and
realtek. I would try defining USE_INTERNAL_BUFFER and see if that might
change your result. Just a thought.

Marty
