<upd_detl>Note copied from 思わしい . We sometimes seem to spell out "negative", sometimes not.
sankoku note: 打ち消しの形で使う

I've also seen the note 《usu. in the negative》.
It appears that as long as the sentence ends up negative, this works, for example:

はかばかしい成果とはいかなかったようだな

(a bunch of negated はかばかしい成果 results at the link).

In fact, uses of はかばかしい are almost all negated: (likewise with はかばかしく + neg. verb)
