question about k1xxd onboard flash..

when you put the flash in manual, does it still emit pre-flashes? if so, are they too fast for the flash to work as an optical trigger for a non-smart sensor?

There is no actual manual mode for the built in flash. The setting described as "manual flash" just means "flash forced on", as opposed to "automatically decide whether a flash is needed". Either way, it does the pre-flash, and that will trigger your non-smart sensor too soon.

Can you expand on the comment "... will trigger your non-smart sensor too soon."?

I worked on that problem the other day with my K100D and a Sigma EF - 500 DG Super

If your flash is anything like mine (I bought it for my Sigma SD14 camera) you can set it up as a slave, and get respectable results.
However you do have to program it manually.

if you want to you can get a general idea of what settings I used on this thread.

If you have any problems with it I might be able to help you out, but I'll be gone for several days. So please don't expect an answer right away.
