Unfortunately there is no SRM for the UX (Ruffian) boards... :-{(
Otherwise we would have done the same as you, long time ago...
I have tried compiling the kernel specifically for Ruffian, but it still
does the same.  It is as if milo itself gets corrupted by Linux, and it 
fails to see the scsi disks after that (even if it still has the driver for
the scsi controller).  I have even tried changing the default driver to
SYM53CXX_2, as it used to be in the old version of the kernel I was using,
but to no avail.  There must be some other dirty trick...
