Getting a bootstrap program to load to a higher address (such as
0x300000) requires some editing of the DVMA code in libsa and recompiling.
Make sure that you change the pre-processor define ``SA_MIN_VA'' in dvma.c
to a higher address.  (The default is 0x200000.)

That, plus changing the link address, should do it.
