FWIW, i hacked up a small driver to read the firmware, i'm attaching it
to this
Mail. Would be nice if some people could try reading the firmware from
their PA-RISC
system so we can collect and archive them. Note that it HPMC's in 32
Bit Mode,
but it worked in 64 Bit mode on my C3750/J5000.
Nice!

Any particular reason you are not simply using BIN_ATTR_RO?
