some small math:
100*75cm should be about 40*30inch which will bring you with 150dpi to
Therefore I do not think that you will be able to supply that shot in a satisfying quality.
@Clickhappy: do you think PS will do miracles and make that size out of a 2.1MP camera?

To be precise, a print of 100x75cm at 150 pixels per inch (not dots per inch, there's a difference) requires an input size of 5906x4429 pixels - or around a 26MP camera if the image goes straight from sensor to output without cropping!
And therein lies the problem with shooting digital I guess... From a 10D/D60 size image, you might be able to interpolate up to that sort of size, but I'm not sure I'd want to hang my reputation on it. From anything much lower resolution, I doubt its going to work. A scan of a slide made by the right professional lab, however, could comfortably get you into that arena.
