As Randy has found the setting of kernel boot time parameters
doesn't work. The problem seems to be that the ide subsystem
asserts ownership over all parameters that start with "ide".
I was unable to bend moduleparam.h to accept a leading underscore
so I went back to the old "__setup" method: the kernel boot time
parameters are now:
   - _ide_scsi_debug + _ide_scsi_suppress_reset

Module load time and sysfs parameters remain the same.

A new patch against lk 2.5.68 is attached.
