Special suru verbs

[datenshi]

Can anyone tell me what the correct negative, potential, passive, volitional, imperative and causative forms of the following 10 special suru verbs are?

愛する
恋する
訳する
欲する
察する
有する
要する
保する
損する
適する

Using various online verb conjugation tools (wiktionary, WWWJDIC, verbix, ...) gives me mixed results, and I'm not sure which ones are correct. The conjugations should follow a pattern like for ichidan and godan verbs, but I don't think all special suru verbs follow the same pattern...

Hope I'm not asking too much, and thank you!

察する	sasshinai	sassaseru?	sassareru?	sasseru	sasshiyō	sasse-(yo), sasshiro
有する	yūshinai, yūsanai	yūsaseru	yūsareru	NA	yūshiyō	yūse-(yo)
要する	yōshinai	yōsaseru	yōsareru	NA	yōshiyō (inferential)	yōse?
損ずる	sonjinai, sonzenai	sonjisaseru	sonzerareru	NA	sonjiyō	sonjiyo, sonzeyo
適する	tekisanai, tekishinai	NA	NA	NA	NA	NA

This is a big table so I may be making more than a few mistakes. Please, oh please help me improve it.

Lacking paradigms are either semantically impossible, practically non-existent, suppleted with the equivalent forms of more regular verbs. Some existing forms are occasional or rarely used.

Wow, thanks a lot! Can I ask why you used 損ずる instead of 損する? Is it more common?

損する	sonshinai	sonsaseru	son-o sareru	NA	sonshiyō	sonshiro

I replaced 損する (to lose as in negotiation, trade; generally do not get enough benefit) with 損ずる (to damage) because the latter is not a compound verb in my view but a verb phrase. As you can see in the passive rubric, the expressions (most of them) sound much more natural with -o suffixed to the noun son.

I see.

I also found this blog post in Japanese that some might find interesting:

Hi again!

I'm wondering which volitional and imperative forms sound better (or in other words, are correct) with short vowel special suru verbs such as:

科する (かする) ->
volitional: かそう or かしよう
imperative: かせ or かしろ/かせよ

資する (しする) ->
volitional: しそう or ししよう
imperative: しせ or ししろ/しせよ

擬する (ぎする) ->
volitional: ぎそう or ぎしよう
imperative: ぎせ or ぎしろ/ぎせよ

And what about the conditional, is it ~せば or ~すれば?

Because "課せば" gives 58,100 results in Google, "課すれば" 5,920, but "資せば" gives 3,650 and "資すれば" 10,500.

Thanks!

Surely the passive and the potential are the other way around, right?

Can we add 罰する to the table? The passive always confuses me.

Also, why did you use romaji... It's so hideous... My poor eyes...

To answer my own question, it seems ~そう for volitional and ~せよ for imperative are more common. For conditional, ~せば, but I'm not sure why it's not so for 資する or for example 比する. This seems random to me.
