mathds and mathbbm don't work with foiltex + 25pt

[Micha Feigin <michf@post.tau.ac.il>]

I can't seem to get foiltex with the 25pt option and the mathds and
mathbbm fonts to play together.
I compiled using pdfelatex and then opened in acroread, but got several
windows one after another of error messages when switching to the page
containing those fonts stating that there was an error opening the
page, a problem with the document (14), couldn't find a font in the
resource dictionary, using helvetica instead and then the page went
white.
Any idea on how to solve this? (I probably need to generate/get/imbed
the fonts or something).

Thanx
