THEORY: A very basic, standard IDE controller *could* work, but to the best of my knowledge none have been reported to work (with SCSI controllers so cheap...). There has also been some conjecture about SATA controllers that may work, esp. if they "look" like IDE controllers to the machine.
I have two Maxtor drives from a couple years ago that have bundled IDE 133 and IDE 133/SATA controllers for PCI bus - I'm planning to give each a try in the near future (I suspect they are *very* standard, and designed to be backwards-compatible for older PCs)...
I also have a couple "Ultra 66" controllers - again, just standard IDE controllers that are twice as fast as the Ultra 33 controller in the Ultra 5/10, I'll give them a try as well - the issue is that the OBP needs to be able to boot off the controller - adding a controller for storage to be accessed only after the OS has booted may be easier/more likely (i.e. boot off IDE/SCSI HD, then use a Solaris 10-supported IDE/SATA controller for storage).
