Yes, there looks something byte swapped. With 1.2 on a Sun SLC, I get the
following with rbootd -d (and it works):
/etc/rbootd.conf:
#8:0:09:10:21:b4                SYS_NBOOT # hp400
8:0:09:10:21:b4         SYS_INST # hp400

rbootd -d:

Note the differences in CTRL, DXSAP and SXSAP. But I'm quite sure that it did
work with some late 1.1 snapshot for SPARC, as I installed my hp400t this way
with 1.1.

PS: Klaus, ich schicke Dir separat mein Binary vom rbootd - ist ja nur 32K
gross...
