My apologies -- after being educated (the version number shown in the
device output is actually the driver version and not a PROM version),
your issue here is likely separate.  The driver revision shown here
is 6.5.3.

Jack should be able to help track this down though...  (I like how
I'm volunteering him for more work, haha.  :-) )
