Hi Marc! Almost all EF lenses, including the two you listed will work on the Canon Digital SLRs. On the Digital SLR they will have 1.5x the magnification that they would have on a 35mm camera. Your 28-90 will be like a 42-135mm and the 75-300 would be like a 112-450mm. This is because the image sensor on the Digital SLR is smaller than a 35mm negative.

Get the Canon EF 70-300mm IS USM about $500 and EFS 17-85mm IS USM about $300. The 75-300 all of them I would not use them 4 a body cap. Camera is fine or step up to XSI.

are your old film lenses FD or EF mounts ?
(Is the old film camera a Canon ?)
EF will fit EFS fine. My expeariance is with the EOS 3000 EF film camera (2002 -etc) and these work fine.
If you have Canon FD, there are some lens converters out there however I have not seen any yet which electrically connect and there is no AF. All Manual focus.
I have used Olympus OM mount adaptors with manual focus to mount older/different mount lenses with some success (As an example).
Best idea is to search ebay for your mount converters.

I hate to re-invent the wheel (and I don't want to cut 'n paste someone else's hard work to present as my own) so please click here for a likely practical solution which usually works and for Canon's own suggestions on the error 99 fault.
If this has assisted you then please rate my answer; if not then add a comment to provide feedback and I'll attempt to provide an alternative solution.
