Muscle spasms (Grand Mal) present risk of drowning (lost regulator) and lung over-expansion injury if ascending. Loss of consciousness presents risk of drowning. Those are both quite clear-cut in relation to diving safety.
Common symptoms of simple partial seizures are:
Complex partial seizures ... may manifest itself as a feeling of déjà vu, jamais vu, fear, euphoria or depersonalization. The seizure aura might also occur as a visual disturbance, such as tunnel vision or a change in the size of objects (macropsia or micropsia). Once consciousness is impaired, the person may display automatisms such as lip smacking, chewing or swallowing. There may also be loss of memory (amnesia) surrounding the seizural event. The person may still be able to perform routine tasks such as walking, although such movements are not purposeful or planned. Witnesses may not recognize that anything is wrong.

I'd suggest that several of those symptoms remained contra-indicative for diving safety. My greatest concern would be those in bold, as these could effect a divers' responsiveness to the environment and psychological state needed for safe diving performance. Basically, a manifestation akin to heavy narcosis coupled with vertigo.... not good.
I'd suggest that even with simple-partial seizures, there remains a case for supervised diving, if diving at all.
Common symptoms of simple partial seizures are:
- preserved consciousness
- sudden and inexplicable feelings of fear, anger, sadness, happiness or nausea
- sensations of falling or movement
- experiencing of unusual feelings or sensations
- altered sense of hearing, smelling, tasting, seeing, and tactile perception (sensory illusions or hallucinations), or feeling as though the environment is not real (derealization) or dissociation from the environment or self (depersonalization)
- a sense of spatial distortion—things close by may appear to be at a distance.
- déjà vu (familiarity) or jamais vu (unfamiliarity)
- laboured speech or inability to speak at all
- usually the event is remembered in detail
