Please take a look at stage2/asm.S, for example. GRUB can switch
between real mode and protected mode. Also, note that PXE has an
interface for protected mode as well.

Would you like to report the problem to the Etherboot people? Because
Etherboot is the upstream project of the network drivers, it is
preferable to fix the problem in Etherboot and propagate the change to
GRUB afterwards. Furthermore, they are probably better at debugging
network drivers than us.
